There is a general understanding that GFP_ATOMIC/GFP_NOWAIT are to be used
from atomic contexts. E.g. from within a spin lock or from the IRQ
context. This is correct but there are some atomic contexts where the
above doesn't hold. One of them would be an NMI context. Page allocator
has never supported that and the general fear of this context didn't let
anybody to actually even try to use the allocator there. Good, but let's
be more specific about that.
Another such a context, and that is where people seem to be more daring,
is raw_spin_lock. Mostly because it simply resembles regular spin lock
which is supported by the allocator and there is not any implementation
difference with !RT kernels in the first place. Be explicit that such a
context is not supported by the allocator. The underlying reason is that
zone->lock would have to become raw_spin_lock as well and that has turned
out to be a problem for RT

Integrate KASAN into KUnit testing framework.
- Fail tests when KASAN reports an error that is not expected
- Use KUNIT_EXPECT_KASAN_FAIL to expect a KASAN error in KASAN
tests
- Expected KASAN reports pass tests and are still printed when run
without kunit_tool (kunit_tool still bypasses the report due to the
test passing)
- KUnit struct in current task used to keep track of the current
test from KASAN code
Make use of "[PATCH v3 kunit-next 1/2] kunit: generalize kunit_resource
API beyond allocated resources" and "[PATCH v3 kunit-next 2/2] kunit: add
support for named resources" from Alan Maguire [1]
- A named resource is added to a test when a KASAN report is
expected
- This resource contains a struct for kasan_data containing
booleans representing if a KASAN report is expected and if a
KASAN report is found

Patch series "KASAN-KUnit Integration", v14.
This patchset contains everything needed to integrate KASAN and KUnit.
KUnit will be able to:
(1) Fail tests when an unexpected KASAN error occurs
(2) Pass tests when an expected KASAN error occurs
Convert KASAN tests to KUnit with the exception of copy_user_test because
KUnit is unable to test those.
Add documentation on how to run the KASAN tests with KUnit and what to
expect when running these tests.
This patch (of 5):
In order to integrate debugging tools like KASAN into the KUnit framework,
add KUnit struct to the current task to keep track of the current KUnit
test.

("mm/fork: Pass new vma pointer into copy_page_range()").
Jason Gunthorpe also reported that the ordering of copy_page_range() is
odd. Since working at it, reorder the parameters to be logical, by (1)
always put the dst_* fields to be before src_* fields, and (2) keep the
same type of parameters together.

Patch series "Fix PageDoubleMap".
This is a purely theoretical problem for now as none of the filesystems
which use PG_private_2 (ie PG_fscache) are being converted at this time,
but it's confusing to leave it like this.
This patch (of 2):
PG_private_2 is defined as being PF_ANY (applicable to tail pages as well
as regular & head pages). That means that the first tail page of a
double-map page will appear to have Private2 set. Use the Workingset bit
instead which is defined as PF_HEAD so any attempt to access the
Workingset bit on a tail page will redirect to the head page's Workingset
bit.

Patch series "Try to release mmap_lock temporarily in smaps_rollup", v4.
Recently, we have observed some janky issues caused by unpleasantly long
contention on mmap_lock which is held by smaps_rollup when probing large
processes. To address the problem, we let smaps_rollup detect if anyone
wants to acquire mmap_lock for write attempts. If yes, just release the
lock temporarily to ease the contention.
smaps_rollup is a procfs interface which allows users to summarize the
process's memory usage without the overhead of seq_* calls. Android uses
it to sample the memory usage of various processes to balance its memory
pool sizes. If no one wants to take the lock for write requests,
smaps_rollup with this patch will behave like the original one.
Although there are on-going mmap_lock optimizations like range-based
locks, the lock applied to smaps_rollup would be the coarse one, which is
hard to avoid the occurrence of aforementioned issues. So the detection
and temporary release for write attempts on mmap_lock in smaps_rollup is
still necessary.
This patch (of 3):
Add new API to query if someone wants to acquire mmap_lock for write
attempts.
Using this instead of rwsem_is_contended makes it more tolerant of future
changes to the lock type.

We account the PTE level of the page tables to the process in order to
make smarter OOM decisions and help diagnose why memory is fragmented.
For these same reasons, we should account pages allocated for PMDs. With
larger process address spaces and ASLR, the number of PMDs in use is
higher than it used to be so the inaccuracy is starting to matter.

The swap page counter is v2 only while memsw is v1 only. As v1 and v2
controllers cannot be active at the same time, there is no point to keep
both swap and memsw page counters in mem_cgroup. The previous patch has
made sure that memsw page counter is updated and accessed only when in v1
code paths. So it is now safe to alias the v1 memsw page counter to v2
swap page counter. This saves 14 long's in the size of mem_cgroup. This
is a saving of 112 bytes for 64-bit archs.
While at it, also document which page counters are used in v1 and/or v2.

We don't initially add anon pages to active lruvec after commit
b518154e59aa ("mm/vmscan: protect the workingset on anonymous LRU").
Remove activate_page() from unuse_pte(), which seems to be missed by the
commit. And make the function static while we are at it.
Before the commit, we called lru_cache_add_active_or_unevictable() to add
new ksm pages to active lruvec. Therefore, activate_page() wasn't
necessary for them in the first place.

SWP_FS is used to make swap_{read,write}page() go through the filesystem,
and it's only used for swap files over NFS for now. Otherwise it will
directly submit IO to blockdev according to swapfile extents reported by
filesystems in advance.
As Matthew pointed out [1], SWP_FS naming is somewhat confusing, so let's
rename to SWP_FS_OPS.

Our users reported that there're some random latency spikes when their RT
process is running. Finally we found that latency spike is caused by
FADV_DONTNEED. Which may call lru_add_drain_all() to drain LRU cache on
remote CPUs, and then waits the per-cpu work to complete. The wait time
is uncertain, which may be tens millisecond.
That behavior is unreasonable, because this process is bound to a specific
CPU and the file is only accessed by itself, IOW, there should be no
pagecache pages on a per-cpu pagevec of a remote CPU. That unreasonable
behavior is partially caused by the wrong comparation of the number of
invalidated pages and the number of the target. For example,
if (count < (end_index - start_index + 1))
The count above is how many pages were invalidated in the local CPU, and
(end_index - start_index + 1) is how many pages should be invalidated.
The usage of (end_index - start_index + 1) is incorrect, because they are
virtual addresses, which may not mapped to pages. Besides that, there may
be holes between start and end. So we'd better check whether there are
still pages on per-cpu pagevec after drain the local cpu, and then decide
whether or not to call lru_add_drain_all().
After I applied it with a hotfix to our production environment, most of
the lru_add_drain_all() can be avoided.

Patch series "Return head pages from find_*_entry", v2.
This patch series started out as part of the THP patch set, but it has
some nice effects along the way and it seems worth splitting it out and
submitting separately.
Currently find_get_entry() and find_lock_entry() return the page
corresponding to the requested index, but the first thing most callers do
is find the head page, which we just threw away. As part of auditing all
the callers, I found some misuses of the APIs and some plain
inefficiencies that I've fixed.
The diffstat is unflattering, but I added more kernel-doc and a new wrapper.
This patch (of 8);
Provide this functionality from the swap cache. It's useful for
more than just mincore().

In support of device-dax growing the ability to front physically
dis-contiguous ranges of memory, update devm_memremap_pages() to track
multiple ranges with a single reference counter and devm instance.
Convert all [devm_]memremap_pages() users to specify the number of ranges
they are mapping in their 'struct dev_pagemap' instance.

The 'struct resource' in 'struct dev_pagemap' is only used for holding
resource span information. The other fields, 'name', 'flags', 'desc',
'parent', 'sibling', and 'child' are all unused wasted space.
This is in preparation for introducing a multi-range extension of
devm_memremap_pages().
The bulk of this change is unwinding all the places internal to libnvdimm
that used 'struct resource' unnecessarily, and replacing instances of
'struct dev_pagemap'.res with 'struct dev_pagemap'.range.
P2PDMA had a minor usage of the resource flags field, but only to report
failures with "%pR". That is replaced with an open coded print of the
range.

In preparation to set a fallback value for dev_dax->target_node, introduce
generic fallback helpers for phys_to_target_node()
A generic implementation based on node-data or memblock was proposed, but
as noted by Mike:
"Here again, I would prefer to add a weak default for
phys_to_target_node() because the "generic" implementation is not really
generic.
The fallback to reserved ranges is x86 specfic because on x86 most of
the reserved areas is not in memblock.memory. AFAIK, no other
architecture does this."
The info message in the generic memory_add_physaddr_to_nid()
implementation is fixed up to properly reflect that
memory_add_physaddr_to_nid() communicates "online" node info and
phys_to_target_node() indicates "target / to-be-onlined" node info.

In preparation for exposing "Soft Reserved" memory ranges without an HMAT,
move the hmem device registration to its own compilation unit and make the
implementation generic.
The generic implementation drops usage acpi_map_pxm_to_online_node() that
was translating ACPI proximity domain values and instead relies on
numa_map_to_online_node() to determine the numa node for the device.

Patch series "device-dax: Support sub-dividing soft-reserved ranges", v5.
The device-dax facility allows an address range to be directly mapped
through a chardev, or optionally hotplugged to the core kernel page
allocator as System-RAM. It is the mechanism for converting persistent
memory (pmem) to be used as another volatile memory pool i.e. the current
Memory Tiering hot topic on linux-mm.
In the case of pmem the nvdimm-namespace-label mechanism can sub-divide
it, but that labeling mechanism is not available / applicable to
soft-reserved ("EFI specific purpose") memory [3]. This series provides a
sysfs-mechanism for the daxctl utility to enable provisioning of
volatile-soft-reserved memory ranges.
The motivations for this facility are:
1/ Allow performance differentiated memory ranges to be split between
kernel-managed and directly-accessed use cases.
2/ Allow physical memory to be provisioned along performance relevant
address boundaries. For example, divide a memory-side cache [4] along
cache-color boundaries.
3/ Parcel out soft-reserved memory to VMs using device-dax as a security
/ permissions boundary [5]. Specifically I have seen people (ab)using
memmap=nn!ss (mark System-RAM as Persistent Memory) just to get the
device-dax interface on custom address ranges. A follow-on for the VM
use case is to teach device-dax to dynamically allocate 'struct page' at
runtime to reduce the duplication of 'struct page' space in both the
guest and the host kernel for the same physical pages.

When enabling CONFIG_TRIM_UNUSED_KSYMS, the linker will warn about the
orphan sections:
(".discard.ksym") is being placed in '".discard.ksym"'
repeatedly when linking vmlinux. This is because the stringification
operator, `#`, in the preprocessor escapes strings. GCC and Clang differ
in how they treat section names that contain \".
The portable solution is to not use a string literal with the preprocessor
stringification operator.

The stringification operator, `#`, in the preprocessor escapes strings.
For example, `# "foo"` becomes `"\"foo\""`. GCC and Clang differ in how
they treat section names that contain \".
The portable solution is to not use a string literal with the preprocessor
stringification operator.
In this case, since __section unconditionally uses the stringification
operator, we actually want the more verbose
__attribute__((__section__())).

As Kees suggests, doing so provides developers with two useful pieces of
information:
- The kernel build was attempting to use GCC.
(Maybe they accidentally poked the wrong configs in a CI.)
- They need 4.9 or better.
("Upgrade to what version?" doesn't need to be dug out of documentation,
headers, etc.)

Patch series "set clang minimum version to 10.0.1", v3.
Adds a compile time #error to compiler-clang.h setting the effective
minimum supported version to clang 10.0.1. A separate patch has already
been picked up into the Documentation/ tree also confirming the version.
Next are a series of reverts. One for 32b arm is a partial revert.
Then Marco suggested fixes to KASAN docs.
Finally, improve the warning for GCC too as per Kees.
This patch (of 7):
During Plumbers 2020, we voted to just support the latest release of Clang
for now. Add a compile time check for this.
We plan to remove workarounds for older versions now, which will break in
subtle and not so subtle ways.

"A decent number of SELinux patches for v5.10, twenty two in total. The
highlights are listed below, but all of the patches pass our test

- A number of changes to how the SELinux policy is loaded and managed
inside the kernel with the goal of improving the atomicity of a
SELinux policy load operation.
These changes account for the bulk of the diffstat as well as the
patch count. A special thanks to everyone who contributed patches
and fixes for this work.
- Convert the SELinux policy read-write lock to RCU.
- A tracepoint was added for audited SELinux access control events;
this should help provide a more unified backtrace across kernel and
userspace.
- Allow the removal of security.selinux xattrs when a SELinux policy
is not loaded.
- Enable policy capabilities in SELinux policies created with the
scripts/selinux/mdp tool.
- Provide some "no sooner than" dates for the SELinux checkreqprot
sysfs deprecation"

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
"The big new thing is the fully lockless ringbuffer implementation,
including the support for continuous lines. It will allow to store and
read messages in any situation wihtout the risk of deadlocks and
without the need of temporary per-CPU buffers.
The access is still serialized by logbuf_lock. It synchronizes few
more operations, for example, temporary buffer for formatting the
message, syslog and kmsg_dump operations. The lock removal is being
discussed and should be ready for the next release.
The continuous lines are handled exactly the same way as before to
avoid regressions in user space. It means that they are appended to
the last message when the caller is the same. Only the last message
can be extended.
The data ring includes plain text of the messages. Except for an
integer at the beginning of each message that points back to the
descriptor ring with other metadata.
The dictionary has to stay. journalctl uses it to filter the log. It
allows to show messages related to a given device. The dictionary
values are stored in the descriptor ring with the other metadata.
This is the first part of the printk rework as discussed at Plumbers
2019, see https://lore.kernel.org/r/87k1acz5rx.fsf@linutronix.de. The
next big step will be handling consoles by kthreads during the normal
system operation. It will require special handling of situations when
the kthreads could not get scheduled, for example, early boot,
suspend, panic.
Other changes:
- Add John Ogness as a reviewer for printk subsystem. He is author of
the rework and is familiar with the code and history.
- Fix locking in serial8250_do_startup() to prevent lockdep report.
- Few code cleanups"

A zoned device with limited resources to open or activate zones may
return an error when the host exceeds those limits. The same command may
be successful if retried later, but the host needs to wait for specific
zone states before it should expect a retry to succeed. Have the block
layer provide an appropriate status for these conditions so applications
can distinuguish this error for special handling.
