Subject: [GIT PULL] vfs fixes

Hey Linus,

/* Summary */
This contains fixes for this merge window:

Misc:
- Don't misleadingly warn during filesystem thaw operations. It's possible that
  a block device which was frozen before it was mounted can cause a failing
  thaw operation if someone concurrently tried to mount it while that thaw
  operation was issued and the device had already been temporarily claimed for
  the mount (The mount will of course be aborted because the device is frozen).

netfs:
- Fix io_uring based write-through. Make sure that the total request length is
  correctly set.
- Fix partial writes to folio tail.
- Remove some xarray helpers that were intended for bounce buffers which got
  defered to a later patch series.
- Make netfs_page_mkwrite() whether folio->mapping is vallid after acquiring
  the folio lock.
- Make netfs_page_mkrite() flush conflicting data instead of waiting.

fsnotify:
- Ensure that fsnotify creation events are generated before fsnotify open
  events when a file is created via ->atomic_open(). The ordering was broken
  before.
- Ensure that no fsnotify events are generated for O_PATH file descriptors.
  While no fsnotify open events were generated, fsnotify close events were.
  Make it consistent and don't produce any.

/* Testing */

gcc: (Debian 13.2.0-25) 13.2.0
