Subject: [GIT PULL] vfs fixes

Hey Linus,

/* Summary */
This contains a few fixes:

afs:

- Fix a lock recursion in afs_wake_up_async_call() on ->notify_lock.

netfs:

- Drop the references to a folio immediately after the folio has been
  extracted to prevent races with future I/O collection.

- Fix a documenation build error.

- Downgrade the i_rwsem for buffered writes to fix a cifs reported
  performance regression when switching to netfslib.

vfs:

- Explicitly return -E2BIG from openat2() if the specified size is
  unexpectedly large. This aligns openat2() with other extensible struct
  based system calls.

- When copying a mount namespace ensure that we only try to remove the
  new copy from the mount namespace rbtree if it has already been added
  to it.

nilfs:

- Clear the buffer delay flag when clearing the buffer state clags when
  a buffer head is discarded to prevent a kernel OOPs.

ocfs2:

- Fix an unitialized value warning in ocfs2_setattr().

proc:

- Fix a kernel doc warning.
