Bring in the changes to the file infrastructure for this cycle. Mostly
cleanups and some performance tweaks.
* file: remove __receive_fd()
* file: stop exposing receive_fd_user()
* fs: replace f_rcuhead with f_task_work
* file: remove pointless wrapper
* file: s/close_fd_get_file()/file_close_fd()/g
* Improve __fget_files_rcu() code generation (and thus __fget_light())
* file: massage cleanup of files that failed to open

When compiling with gcc version 14.0.0 20231220 (experimental)
and W=1, I've noticed the following warning:
kernel/watch_queue.c: In function 'watch_queue_set_size':
kernel/watch_queue.c:273:32: warning: 'kcalloc' sizes specified with 'sizeof'
in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
273 | pages = kcalloc(sizeof(struct page *), nr_pages, GFP_KERNEL);
| ^~~~~~
Since 'n' and 'size' arguments of 'kcalloc()' are multiplied to
calculate the final size, their actual order doesn't affect the
result and so this is not a bug. But it's still worth to fix it.

When mapping a file on overlayfs, the file stored in ->vm_file is a
backing file whose f_inode is on the underlying filesystem. We need to
verify that /proc/pid/maps contains numbers of the overlayfs file, but
not its backing file.

/proc/pid/maps shows device and inode numbers of vma->vm_file-s. Here is
an issue. If a mapped file is on a stackable file system (e.g.,
overlayfs), vma->vm_file is a backing file whose f_inode is on the
underlying filesystem. To show correct numbers, we need to get a user
file and shows its numbers. The same trick is used to show file paths in
/proc/pid/maps.

There is no reason to use a GFP_USER flag for struct super_block allocation
in the alloc_super(). Instead, let's use GFP_KERNEL for that.
>From the memory management perspective, the only difference between
GFP_USER and GFP_KERNEL is that GFP_USER allocations are tied to a cpuset,
while GFP_KERNEL ones are not.
There is no real issue and this is not a candidate to go to the stable,
but let's fix it for a consistency sake.

Commit c73be61cede5 ("pipe: Add general notification queue support") a
regression was introduced that would lock up resized pipes under certain
conditions. See the reproducer in [1].
The commit resizing the pipe ring size was moved to a different
function, doing that moved the wakeup for pipe->wr_wait before actually
raising pipe->max_usage. If a pipe was full before the resize occured it
would result in the wakeup never actually triggering pipe_write.
Set @max_usage and @nr_accounted before waking writers if this isn't a
watch queue.

Honestly, there's little value in having a helper with and without that
int __user *ufd argument. It's just messy and doesn't really give us

Only io_uring uses __close_fd_get_file(). All it does is hide
current->files but io_uring accesses files_struct directly right now
anyway so it's a bit pointless. Just rename pick_file() to
file_close_fd_locked() and let io_uring use it. Add a lockdep assert in
there that we expect the caller to hold file_lock while we're at it.

That really shouldn't have "get" in there as that implies we're bumping

Now we're just closing the fd and pick that file from the fdtable
without bumping the reference count. Update the wrong documentation

Commit 0ede61d8589c ("file: convert to SLAB_TYPESAFE_BY_RCU") caused a
performance regression as reported by the kernel test robot.
The __fget_light() function is one of those critical ones for some

write that function to better.

A file that has never gotten FMODE_OPENED will never have RCU-accessed
references, its final fput() is equivalent to file_free() and if it
doesn't have FMODE_BACKING either, it can be done from any context and
won't need task_work treatment.
Now that we have SLAB_TYPESAFE_BY_RCU we can simplify this and have
other callers benefit. All of that can be achieved easier is to make
fput() recoginze that case and call file_free() directly.
No need to introduce a special primitive for that. It also allowed
things like failing dentry_open() could benefit from that as well.

When you try to splice between a normal pipe and a notification pipe,
get_pipe_info(..., true) fails, so splice() falls back to treating the
notification pipe like a normal pipe - so we end up in
iter_file_splice_write(), which first locks the input pipe, then calls
vfs_iter_write(), which locks the output pipe.
Lockdep complains about that, because we're taking a pipe lock while
already holding another pipe lock.
I think this probably (?) can't actually lead to deadlocks, since you'd
need another way to nest locking a normal pipe into locking a
watch_queue pipe, but the lockdep annotations don't make that clear.
Bail out earlier in pipe_write() for notification pipes, before taking
the pipe lock.

There's no reason we need to couple mnt idmapping to namespaces in the
way we currently do. Copy the idmapping when an idmapped mount is
created and don't take any reference on the namespace at all.
We also can't easily refcount struct uid_gid_map because it needs to
stay the size of a cacheline otherwise we risk performance regressions
(Ignoring for a second that right now struct uid_gid_map isn't actually
64 byte but 72 but that's a fix for another patch series.).

All mounts default to nop_mnt_idmap and we don't allow creating idmapped
mounts that reuse the idmapping of the filesystem. So unless someone
passes a non-superblock namespace to these helpers this check will
always be false. Remove it and replace it with a simple check for
nop_mnt_idmap.

I've been observing workloads where IPIs due to wakeups in
aio_complete() are ~15% of total CPU time in the profile. Most of those
wakeups are unnecessary when completion batching is in use in
io_getevents().
This plumbs min_nr through via the wait eventry, so that aio_complete()
can avoid doing unnecessary wakeups.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull probes fixes from Masami Hiramatsu:
- Documentation update: Add a note about argument and return value
fetching is the best effort because it depends on the type.
- objpool: Fix to make internal global variables static in
test_objpool.c.
- kprobes: Unify kprobes_exceptions_nofify() prototypes. There are the
same prototypes in asm/kprobes.h for some architectures, but some of
them are missing the prototype and it causes a warning. So move the
prototype into linux/kprobes.h.
- tracing: Fix to check the tracepoint event and return event at
parsing stage. The tracepoint event doesn't support %return but if
$retval exists, it will be converted to %return silently. This finds
that case and rejects it.
- tracing: Fix the order of the descriptions about the parameters of
__kprobe_event_gen_cmd_start() to be consistent with the argument
list of the function.

The order of descriptions should be consistent with the argument list of
the function, so "kretprobe" should be the second one.

- Move the MediaTek GIC quirk handling from irqchip to core. Before

pseudo NMIs on MediaTek devices w/ firmware issues") temporarily
addressed this issue. Fixed now at a deeper level in the arch code

otherwise some of the core PMU events would disappear
- Fix the Armv8 PMUv3 driver driver to not truncate 64-bit registers,
causing some events to be invisible

patch to avoid prototype warning for syscalls
