Pull xfs updates from Darrick Wong:
"There are quite a few changes in this release, the most notable of
which is that we've made inode flushing fully asynchronous, and we no
longer block memory reclaim on this.
Furthermore, we have fixed a long-standing bug in the quota code where
soft limit warnings and inode limits were never tracked properly.
Moving further down the line, the reflink control loops have been
redesigned to behave more efficiently; and numerous small bugs have
been fixed (see below). The xattr and quota code have been extensively
refactored in preparation for more new features coming down the line.
Finally, the behavior of DAX between ext4 and xfs has been stabilized,
which gets us a step closer to removing the experimental tag from that
feature.
We have a few new contributors this time around. Welcome, all!
I anticipate a second pull request next week for a few small bugfixes
that have been trickling in, but this is it for big changes.
Summary:
- Fix some btree block pingponging problems when swapping extents
- Redesign the reflink copy loop so that we only run one remapping
operation per transaction. This helps us avoid running out of block
reservation on highly deduped filesystems.
- Take the MMAPLOCK around filemap_map_pages.
- Make inode reclaim fully async so that we avoid stalling processes
on flushing inodes to disk.
- Reduce inode cluster buffer RMW cycles by attaching the buffer to
dirty inodes so we won't let go of the cluster buffer when we know
we're going to need it soon.
- Add some more checks to the realtime bitmap file scrubber.
- Don't trip false lockdep warnings in fs freeze.
- Remove various redundant lines of code.
- Remove unnecessary calls to xfs_perag_{get,put}.
- Preserve I_VERSION state across remounts.
- Fix an unmount hang due to AIL going to sleep with a non-empty
delwri buffer list.
- Fix an error in the inode allocation space reservation macro that
caused regressions in generic/531.
- Fix a potential livelock when dquot flush fails because the dquot
buffer is locked.
- Fix a miscalculation when reserving inode quota that could cause
users to exceed a hardlimit.
- Refactor struct xfs_dquot to use native types for incore fields
instead of abusing the ondisk struct for this purpose. This will
eventually enable proper y2038+ support, but for now it merely
cleans up the quota function declarations.
- Actually increment the quota softlimit warning counter so that soft
failures turn into hard(er) failures when they exceed the softlimit
warning counter limits set by the administrator.
- Split incore dquot state flags into their own field and namespace,
to avoid mixing them with quota type flags.
- Create a new quota type flags namespace so that we can make it
obvious when a quota function takes a quota type (user, group,
project) as an argument.
- Rename the ondisk dquot flags field to type, as that more
accurately represents what we store in it.
- Drop our bespoke memory allocation flags in favor of GFP_*.
- Rearrange the xattr functions so that we no longer mix metadata
updates and transaction management (e.g. rolling complex
transactions) in the same functions. This work will prepare us for
atomic xattr operations (itself a prerequisite for directory
backrefs) in future release cycles.
- Support FS_DAX_FL (aka FS_XFLAG_DAX) via GETFLAGS/SETFLAGS"

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
- Add support for (optionally) using queued spinlocks & rwlocks.
- Support for a new faster system call ABI using the scv instruction on
Power9 or later.
- Drop support for the PROT_SAO mmap/mprotect flag as it will be
unsupported on Power10 and future processors, leaving us with no way
to implement the functionality it requests. This risks breaking
userspace, though we believe it is unused in practice.
- A bug fix for, and then the removal of, our custom stack expansion
checking. We now allow stack expansion up to the rlimit, like other
architectures.
- Remove the remnants of our (previously disabled) topology update
code, which tried to react to NUMA layout changes on virtualised
systems, but was prone to crashes and other problems.
- Add PMU support for Power10 CPUs.
- A change to our signal trampoline so that we don't unbalance the link
stack (branch return predictor) in the signal delivery path.
- Lots of other cleanups, refactorings, smaller features and so on as
usual.

The code for preallocate_vmalloc_pages() was written under the
assumption that the p4d_offset() and pud_offset() functions will perform
present checks before dereferencing the parent entries.
This assumption is wrong an leads to a bug in the code which causes the
physical address found in the PGD be used as a page-table page, even if
the PGD is not present.
So the code flow currently is:
pgd = pgd_offset_k(addr);
p4d = p4d_offset(pgd, addr);
if (p4d_none(*p4d))
p4d = p4d_alloc(&init_mm, pgd, addr);
This lacks a check for pgd_none() at least, the correct flow would be:
pgd = pgd_offset_k(addr);
if (pgd_none(*pgd))
p4d = p4d_alloc(&init_mm, pgd, addr);
else
p4d = p4d_offset(pgd, addr);
But this is the same flow that the p4d_alloc() and the pud_alloc()
functions use internally, so there is no need to duplicate them.
Remove the p?d_none() checks from the function and just call into
p4d_alloc() and pud_alloc() to correctly pre-allocate the PGD entries.

Commit 585524081ecd ("random: random.h should include archrandom.h, not
the other way around") tries to fix a problem with recursive inclusion
of linux/random.h and arch/archrandom.h for arm64. Unfortunately, this
results in the following compile error if ARCH_RANDOM is disabled.
arch/arm64/kernel/kaslr.c: In function 'kaslr_early_init':
arch/arm64/kernel/kaslr.c:128:6: error: implicit declaration of function '__early_cpu_has_rndr'; did you mean '__early_pfn_to_nid'? [-Werror=implicit-function-declaration]
if (__early_cpu_has_rndr()) {
^~~~~~~~~~~~~~~~~~~~
__early_pfn_to_nid
arch/arm64/kernel/kaslr.c:131:7: error: implicit declaration of function '__arm64_rndr' [-Werror=implicit-function-declaration]
if (__arm64_rndr(&raw))
^~~~~~~~~~~~
The problem is that arch/archrandom.h is only included from
linux/random.h if ARCH_RANDOM is enabled. If not, __arm64_rndr() and
__early_cpu_has_rndr() are undeclared, causing the problem.
Use arch_get_random_seed_long_early() instead of arm64 specific
functions to solve the problem.

We just don't do that. "default y" is for things that are needed for
compatibility (when an old feature is made unconditional), or for things
that are basically part of the infrastructure of a platform.
And it can possibly be used for questions that don't enable code on
their own, but are used to enable or disable a whole slew of other
questions.
A new feature that people aren't using is never 'default y', unless it
cures cancer or ends world hunger.

"The most notable changes are:
- iomap no longer invalidates the page cache when performing a direct

trigger falling back to a buffered write since ext4 already did
this and btrfs wants it for their port.
- iomap falls back to buffered writes if we're doing a direct write
and the page cache invalidation after the flush fails; this was
necessary to handle a corner case in the btrfs port.

This reverts commit 8bb9bf242d1fee925636353807c511d54fde8986.
It seems the vmalloc page tables aren't always preallocated in all
situations, because Jason Donenfeld reports an oops with this commit:
BUG: unable to handle page fault for address: ffffe8ffffd00608
#PF: supervisor read access in kernel mode
#PF: error_code(0x0000) - not-present page
PGD 0 P4D 0

CR2: ffffe8ffffd00608
and that page fault address is right in that vmalloc space, and we
clearly don't have a PGD/P4D entry for it.
Looking at the "Code:" line, the actual fault seems to come from the
'pwq->wq' dereference at the top of the process_one_work() function:
struct pool_workqueue *pwq = get_work_pwq(work);
struct worker_pool *pool = worker->pool;
bool cpu_intensive = pwq->wq->flags & WQ_CPU_INTENSIVE;
so 'struct pool_workqueue *pwq' is the allocation that hasn't been
synchronized across CPUs.
Just revert for now, while Joerg figures out the cause.

Pull sched/fifo updates from Ingo Molnar:
"This adds the sched_set_fifo*() encapsulation APIs to remove static
priority level knowledge from non-scheduler code.
The three APIs for non-scheduler code to set SCHED_FIFO are:
- sched_set_fifo()
- sched_set_fifo_low()
- sched_set_normal()
These are two FIFO priority levels: default (high), and a 'low'
priority level, plus sched_set_normal() to set the policy back to
non-SCHED_FIFO.
Since the changes affect a lot of non-scheduler code, we kept this in
a separate tree"

During my code inspection I saw there is no implementation of a graceful
shutdown for tcp. This patch will introduce a graceful shutdown for tcp
connections. The shutdown is implemented synchronized as
dlm_lowcomms_stop() is called to end all dlm communication. After shutdown
is done, a lot of flush and closing functionality will be called. However
I don't see a problem with that.
The waitqueue for synchronize the shutdown has a timeout of 10 seconds, if
timeout a force close will be exectued.

This patch changes the handling of reconnects. At first we only close
the connection related to the communication failure. If we get a new
connection for an already existing connection we close the existing
connection and take the new one.
This patch improves significantly the stability of tcp connections while
running "tcpkill -9 -i $IFACE port 21064" while generating a lot of dlm
messages e.g. on a gfs2 mount with many files. My test setup shows that a
deadlock is "more" unlikely. Before this patch I wasn't able to get
not a deadlock after 5 seconds. After this patch my observation is
that it's more likely to survive after 5 seconds and more, but still a
deadlock occurs after certain time. My guess is that there are still
"segments" inside the tcp writequeue or retransmit queue which get dropped
when receiving a tcp reset [1]. Hard to reproduce because the right message
need to be inside these queues, which might even be in the 5 first seconds
with this patch.

This patch doesn't close sockets when there is an invalid dlm message
received. The connection will probably reconnect anyway so. To not
close the connection will reduce the number of possible failtures.
As we don't have a different strategy to react on such scenario
just keep going the connection and ignore the message.

Currently the error return path from kobject_init_and_add() is not
followed by a call to kobject_put() - which means we are leaking
the kobject.
Set do_unreg = 1 before kobject_init_and_add() to ensure that
kobject_put() can be called in its error patch.

Oliver Neukum says:
====================
misc bug fixes for the hso driver
1. Code reuse led to an unregistration of a net driver that has not been
registered
2. The kernel complains generically if kmalloc with GFP_KERNEL fails
3. A race that can lead to an URB that is in use being reused or
a use after free

This check an inherent race. It opens a race where
an error code has already been set or cleared yet
the URB has not been given back. We cannot do
such an optimization and must unlink unconditionally.
