Merge tag 'vfs-6.11-rc7.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs fixes from Christian Brauner:
 "Two netfs fixes for this merge window:

   - Ensure that fscache_cookie_lru_time is deleted when the fscache
     module is removed to prevent UAF

   - Fix filemap_invalidate_inode() to use invalidate_inode_pages2_range()

     Before it used truncate_inode_pages_partial() which causes
     copy_file_range() to fail on cifs"

* tag 'vfs-6.11-rc7.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  fscache: delete fscache_cookie_lru_timer when fscache exits to avoid UAF
  mm: Fix filemap_invalidate_inode() to use invalidate_inode_pages2_range()
