Add a trace_nfs4_offload_status trace point that looks just like
trace_nfs4_offload_cancel. Promote that event to an event class to
avoid duplicating code.
An alternative approach would be to expand trace_nfs4_offload_status
to report more of the actual OFFLOAD_STATUS result.

We've found that there are cases where a transport disconnection
results in the loss of callback RPCs. NFS servers typically do not
retransmit callback operations after a disconnect.
This can be a problem for the Linux NFS client's current
implementation of asynchronous COPY, which waits indefinitely for a
CB_OFFLOAD callback. If a transport disconnect occurs while an async
COPY is running, there's a good chance the client will never get the
completing CB_OFFLOAD.
Fix this by implementing the OFFLOAD_STATUS operation so that the
Linux NFS client can probe the NFS server if it doesn't see a
CB_OFFLOAD in a reasonable amount of time.
This patch implements a simplistic check. As future work, the client
might also be able to detect whether there is no forward progress on
the request asynchronous COPY operation, and CANCEL it.

A recent change increased the size of an NFSv4 open owner, but didn't
increase the corresponding max_sz defines. This is not know to have
caused failure, but should be fixed.
This patch also fixes some relates _maxsz fields that are wrong.
Note that the XXX_owner_id_maxsz values now are only the size of the id
and do NOT include the len field that will always preceed the id in xdr
encoding. I think this is clearer.

====================
Support freplace prog from user namespace
From: Mykyta Yatsenko <yatsenko@meta.com>
Freplace programs can't be loaded from user namespace, as
bpf_program__set_attach_target() requires searching for target prog BTF,
which is locked under CAP_SYS_ADMIN.
This patch set enables this use case by:
1. Relaxing capable check in bpf's BPF_BTF_GET_FD_BY_ID, check for CAP_BPF
instead of CAP_SYS_ADMIN, support BPF token in attr argument.
2. Pass BPF token around libbpf from bpf_program__set_attach_target() to
bpf syscall where capable check is.
3. Validate positive/negative scenarios in selftests
This patch set is enabled by the recent libbpf change[1], that
introduced bpf_object__prepare() API. Calling bpf_object__prepare() for
freplace program before bpf_program__set_attach_target() initializes BPF
token, which is then passed to bpf syscall by libbpf.

While the network device is registered, it is published to userspace,
and thus userspace can change its state. This means calling
functions such as stmmac_stop_all_dma() and stmmac_mac_set() are
racy.
Moreover, unregister_netdev() will unpublish the network device, and
then if appropriate call the .ndo_stop() method, which is
stmmac_release(). This will first call phylink_stop() which will
synchronously take the link down, resulting in stmmac_mac_link_down()
and stmmac_mac_set(, false) being called.
stmmac_release() will also call stmmac_stop_all_dma().
Consequently, neither of these two functions need to called prior
to unregister_netdev() as that will safely call paths that will
result in this work being done if necessary.
Remove these redundant racy calls.

Lenovo ThinkPad Hybrid USB-C with USB-A Dock (17ef:a359) is affected by
the same problem as the Lenovo Powered USB-C Travel Hub (17ef:721e):
Both are based on the Realtek RTL8153B chip used to use the cdc_ether
driver. However, using this driver, with the system suspended the device
constantly sends pause-frames as soon as the receive buffer fills up.
This causes issues with other devices, where some Ethernet switches stop
forwarding packets altogether.
Using the Realtek driver (r8152) fixes this issue. Pause frames are no
longer sent while the host system is suspended.

"cpu_addr" is a misnomer because when a bus fabric translates addresses
between the CPU and the ATU, the ATU input address is different from the
CPU address. A future patch will rename "cpu_addr" and correct the value
to be the ATU input address instead of the CPU physical address.

The UEFI Specification version 2.9 introduces the concept of memory
acceptance: some Virtual Machine platforms, such as Intel TDX or AMD
SEV-SNP, require memory to be accepted before it can be used by the guest.
Accepting memory is expensive. The memory must be allocated by the VMM
and then brought to a known safe state: cache must be flushed, memory must
be zeroed with the guest's encryption key, and associated metadata must be
manipulated. These operations must be performed from a trusted
environment (firmware or TDX module). Switching context to and from it
also takes time.
This cost adds up. On large confidential VMs, memory acceptance alone can
take minutes. It is better to delay memory acceptance until the memory is
actually needed.
The kernel accepts memory when it is allocated from buddy allocator for
the first time. This reduces boot time and decreases memory overhead as
the VMM can allocate memory as needed.
It does not work when the guest attempts to kexec into a new kernel.
The kexec segments' destination addresses are not allocated by the buddy
allocator. Instead, they are searched from normal system RAM (top-down or
bottom-up) and exclude driver-managed memory, ACPI, persistent, and
reserved memory. Unaccepted memory is normal system RAM from kernel point
of view and kexec can place segments there.
Kexec bypasses the code path in buddy allocator where memory gets accepted
and it leads to a crash when kexec accesses segments' memory.
Accept the destination addresses during the kexec load, immediately after
they pass sanity checks. This ensures the code is located in a common
place shared by both the kexec_load and kexec_file_load system calls.
This will not conflict with the accounting in try_to_accept_memory_one()
since the accounting is set during kernel boot and decremented when pages
are moved to the freelists. There is no harm in invoking accept_memory()
on a page before making it available to the buddy allocator.
No need to worry about re-accepting memory since accept_memory() checks
the unaccepted bitmap before accepting a memory page.
Although a user may perform kexec loading without ever triggering the
jump, it doesn't impact much since kexec loading is not in a
performance-critical path. Additionally, the destination addresses are
always searched and found in the same location on a given system.
Changes to the destination address searching logic to locate only memory in
either unaccepted or accepted status are unnecessary and complicated.

Currently, up to 23 bytes of the source string are copied to the
destination buffer (including the comma and anything after it), only to
then manually NUL-terminate the destination buffer again at index 'len'
(where the comma was found).
Fix this by calling strscpy() with 'len' instead of the destination buffer
size to copy only as many bytes from the source string as needed.
Change the length check to allow 'len' to be less than or equal to the
destination buffer size to fill the whole buffer if needed.
Remove the if-check for the return value of strscpy(), because calling
strscpy() with 'len' always truncates the source string at the comma as
expected and NUL-terminates the destination buffer at the corresponding
index instead. Remove the manual NUL-termination.
No functional changes intended.

The interval_tree_subtree_search() holds the loop invariant:
start <= node->ITSUBTREE
Let's say we have a following tree:
node
/ \
left right
So we know node->ITSUBTREE is contributed by one of the following:
* left->ITSUBTREE
* ITLAST(node)
* right->ITSUBTREE
When we come to the right node, we are sure the first two don't
contribute to node->ITSUBTREE and it must be the right node does the
job.
So skip the check before go to the right subtree.

Current test use pseudo rand function with fixed seed, which means the
test data is the same pattern each time.
Add random seed parameter to randomize the test.

Current tests are gathered in one big function.
Split tests into its own function for better understanding and also it
is a preparation for introducing new test cases.

Patch series "lib/interval_tree: add some test cases and cleanup", v2.
Since rbtree/augmented tree/interval tree share similar data structure,
besides new cases for interval tree, this patch set also does cleanup for
others.
This patch (of 7):
Currently we have some tests for rbtree related data structure, e.g.
rbtree, augmented rbtree, interval tree, in lib/ as kernel module.
To facilitate the test and debug for those fundamental data structure,
this patch enable those tests in userland.

Neither the warning nor the help message gives any hint on the unit for
length: Could be meters, inches, bytes, characters or ... lines.
Extend the output of `--help` to name the unit "lines" and the default:
- --min-conf-desc-length=n set the min description length, if shorter, warn
+ --min-conf-desc-length=n set the minimum description length for config symbols
+ in lines, if shorter, warn (default 4)
Include the minimum number of lines as other error messages already do:
- WARNING: please write a help paragraph that fully describes the config symbol
+ WARNING: please write a help paragraph that fully describes the config symbol with at least 4 lines

Use QEMU's qemu.PhyMemMode [1] functionality to read vmcore from the
physical memory the same way the existing dump tooling does this.
Gracefully handle non-QEMU targets, early boot, and memory corruptions;
print a warning if such situation is detected.

Clearing is an atomic op and the flag is not set most of the time.
When creating and destroying threads in the same process with the pthread
family, the primary bottleneck is calls to sigprocmask which take the
process-wide sighand lock.
Avoiding the atomic gives me a 2% bump in start/teardown rate at 24-core
scale.
[akpm@linux-foundation.org: add unlikely() as well]

When loading symbols from kernel modules we used to iterate
from 0 to module_sect_attrs::nsections, in order to
retrieve their name and address.
However module_sect_attrs::nsections has been removed from
the struct by a previous commit.
Re-arrange the iteration by accessing all items in
module_sect_attrs::grp::bin_attrs[] until NULL is found
(it's a NULL terminated array).
At the same time the symbol address cannot be extracted
from module_sect_attrs::attrs[]::address anymore because
it has also been deleted. Fetch it from
module_sect_attrs::grp::bin_attrs[]::private as described
in 4b2c11e4aaf7.
