Pull vfs fixes from Christian Brauner:
 "cachefiles:

   - Export an existing and add a new cachefile helper to be used in
     filesystems to fix reference count bugs

   - Use the newly added fscache_ty_get_volume() helper to get a
     reference count on an fscache_volume to handle volumes that are
     about to be removed cleanly

   - After withdrawing a fscache_cache via FSCACHE_CACHE_IS_WITHDRAWN
     wait for all ongoing cookie lookups to complete and for the object
     count to reach zero

   - Propagate errors from vfs_getxattr() to avoid an infinite loop in
     cachefiles_check_volume_xattr() because it keeps seeing ESTALE

   - Don't send new requests when an object is dropped by raising
     CACHEFILES_ONDEMAND_OJBSTATE_DROPPING

   - Cancel all requests for an object that is about to be dropped

   - Wait for the ondemand_boject_worker to finish before dropping a
     cachefiles object to prevent use-after-free

   - Use cyclic allocation for message ids to better handle id recycling

   - Add missing lock protection when iterating through the xarray when
     polling

  netfs:

   - Use standard logging helpers for debug logging

  VFS:

   - Fix potential use-after-free in file locks during
     trace_posix_lock_inode(). The tracepoint could fire while another
     task raced it and freed the lock that was requested to be traced

   - Only increment the nr_dentry_negative counter for dentries that are
     present on the superblock LRU. Currently, DCACHE_LRU_LIST list is
     used to detect this case. However, the flag is also raised in
     combination with DCACHE_SHRINK_LIST to indicate that dentry->d_lru
     is used. So checking only DCACHE_LRU_LIST will lead to wrong
     nr_dentry_negative count. Fix the check to not count dentries that
     are on a shrink related list

  Misc:

   - hfsplus: fix an uninitialized value issue in copy_name

   - minix: fix minixfs_rename with HIGHMEM. It still uses kunmap() even
     though we switched it to kmap_local_page() a while ago"
