Merge tag 'vfs-6.10-rc8.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
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" * tag 'vfs-6.10-rc8.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: minixfs: Fix minixfs_rename with HIGHMEM hfsplus: fix uninit-value in copy_name vfs: don't mod negative dentry count when on shrinker list filelock: fix potential use-after-free in posix_lock_inode cachefiles: add missing lock protection when polling cachefiles: cyclic allocation of msg_id to avoid reuse cachefiles: wait for ondemand_object_worker to finish when dropping object cachefiles: cancel all requests for the object that is being dropped cachefiles: stop sending new request when dropping object cachefiles: propagate errors from vfs_getxattr() to avoid infinite loop cachefiles: fix slab-use-after-free in cachefiles_withdraw_cookie() cachefiles: fix slab-use-after-free in fscache_withdraw_volume() netfs, fscache: export fscache_put_volume() and add fscache_try_get_volume() netfs: Switch debug logging to pr_debug()
