879fb3c274 slab: add struct kmem_cache_args
Currently we have multiple kmem_cache_create*() variants that take up to
seven separate parameters with one of the functions having to grow an
eigth parameter in the future to handle both usercopy and a custom
freelist pointer.

Add a struct kmem_cache_args structure and move less common parameters
into it. Core parameters such as name, object size, and flags continue
to be passed separately.

Add a new function __kmem_cache_create_args() that takes a struct
kmem_cache_args pointer and port do_kmem_cache_create_usercopy() over to
it.

In follow-up patches we will port the other kmem_cache_create*()
variants over to it as well.

dfdc8d2565 Merge patch series "fs,mm: add kmem_cache_create_rcu()"
Christian Brauner <brauner@kernel.org> says:

When a kmem cache is created with SLAB_TYPESAFE_BY_RCU the free pointer
must be located outside of the object because we don't know what part of
the memory can safely be overwritten as it may be needed to prevent
object recycling.

That has the consequence that SLAB_TYPESAFE_BY_RCU may end up adding a
new cacheline. This is the case for e.g., struct file. After having it
shrunk down by 40 bytes and having it fit in three cachelines we still
have SLAB_TYPESAFE_BY_RCU adding a fourth cacheline because it needs to
accommodate the free pointer.

Add a new kmem_cache_create_rcu() function that allows the caller to
specify an offset where the free pointer is supposed to be placed.

Before this series cat /proc/slabinfo:

filp                1198   1248    256   32    2 : tunables    0    0    0 : slabdata     39     39      0

c0390d5411 fs: pack struct file
Now that we shrunk struct file to 192 bytes aka 3 cachelines reorder
struct file to not leave any holes or have members cross cachelines.

Add a short comment to each of the fields and mark the cachelines.
It's possible that we may have to tweak this based on profiling in the
future. So far I had Jens test this comparing io_uring with non-fixed
and fixed files and it improved performance. The layout is a combination
of Jens' and my changes.

a55d1cbd17 fs: switch f_iocb_flags and f_ra
Now that we shrank struct file by 24 bytes we still have a 4 byte hole.
If we move struct file_ra_state into the union and f_iocb_flags out of
the union we close that whole and bring down struct file to 192 bytes.
Which means struct file is 3 cachelines and we managed to shrink it by
40 bytes this cycle.

I've tried to audit all codepaths that use f_ra and none of them seem to
rely on it in file->f_op->release() and never have since commit
1da177e4c3 ("Linux-2.6.12-rc2").

1934b21261 file: reclaim 24 bytes from f_owner
We do embedd struct fown_struct into struct file letting it take up 32
bytes in total. We could tweak struct fown_struct to be more compact but
really it shouldn't even be embedded in struct file in the first place.

Instead, actual users of struct fown_struct should allocate the struct
on demand. This frees up 24 bytes in struct file.

That will have some potentially user-visible changes for the ownership
fcntl()s. Some of them can now fail due to allocation failures.
Practically, that probably will almost never happen as the allocations
are small and they only happen once per file.

The fown_struct is used during kill_fasync() which is used by e.g.,
pipes to generate a SIGIO signal. Sending of such signals is conditional
on userspace having set an owner for the file using one of the F_OWNER
fcntl()s. Such users will be unaffected if struct fown_struct is
allocated during the fcntl() call.

There are a few subsystems that call __f_setown() expecting
file->f_owner to be allocated:

(1) tun devices
    file->f_op->fasync::tun_chr_fasync()
    -> __f_setown()

    There are no callers of tun_chr_fasync().

(2) tty devices

    file->f_op->fasync::tty_fasync()
    -> __tty_fasync()
       -> __f_setown()

    tty_fasync() has no additional callers but __tty_fasync() has. Note
    that __tty_fasync() only calls __f_setown() if the @on argument is
    true. It's called from:

    file->f_op->release::tty_release()
    -> tty_release()
       -> __tty_fasync()
          -> __f_setown()

    tty_release() calls __tty_fasync() with @on false
    => __f_setown() is never called from tty_release().
       => All callers of tty_release() are safe as well.

    file->f_op->release::tty_open()
    -> tty_release()
       -> __tty_fasync()
          -> __f_setown()

    __tty_hangup() calls __tty_fasync() with @on false
    => __f_setown() is never called from tty_release().
       => All callers of __tty_hangup() are safe as well.

From the callchains it's obvious that (1) and (2) end up getting called
via file->f_op->fasync(). That can happen either through the F_SETFL
fcntl() with the FASYNC flag raised or via the FIOASYNC ioctl(). If
FASYNC is requested and the file isn't already FASYNC then
file->f_op->fasync() is called with @on true which ends up causing both
(1) and (2) to call __f_setown().

(1) and (2) are the only subsystems that call __f_setown() from the
file->f_op->fasync() handler. So both (1) and (2) have been updated to
allocate a struct fown_struct prior to calling fasync_helper() to
register with the fasync infrastructure. That's safe as they both call
fasync_helper() which also does allocations if @on is true.

The other interesting case are file leases:

(3) file leases
    lease_manager_ops->lm_setup::lease_setup()
    -> __f_setown()

    Which in turn is called from:

    generic_add_lease()
    -> lease_manager_ops->lm_setup::lease_setup()
       -> __f_setown()

So here again we can simply make generic_add_lease() allocate struct
fown_struct prior to the lease_manager_ops->lm_setup::lease_setup()
which happens under a spinlock.

With that the two remaining subsystems that call __f_setown() are:

(4) dnotify
(5) sockets

Both have their own custom ioctls to set struct fown_struct and both
have been converted to allocate a struct fown_struct on demand from
their respective ioctls.

Interactions with O_PATH are fine as well e.g., when opening a /dev/tty
as O_PATH then no file->f_op->open() happens thus no file->f_owner is
allocated. That's fine as no file operation will be set for those and
the device has never been opened. fcntl()s called on such things will
just allocate a ->f_owner on demand. Although I have zero idea why'd you
care about f_owner on an O_PATH fd.

95832998fb nfs: fix bitmap decoder to handle a 3rd word
It only decodes the first two words at this point. Have it decode the
third word as well. Without this, the client doesn't send delegated

With this change we also need to expand the on-stack bitmap in
