Hello Linus,
could you please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs.git fsnotify_for_v5.16-rc1
to get support for reporting filesystem errors through fanotify so that
system health monitoring daemons can watch for these and act instead of
scraping system logs.
Top of the tree is 15c72660fe9a. The full shortlog is:
Amir Goldstein (3):
fsnotify: pass data_type to fsnotify_name()

fanotify: Fold event size calculation to its own function
fanotify: Split fsid check from other fid mode checks
inotify: Don't force FS_IN_IGNORED
fsnotify: Add helper to detect overflow_event
fsnotify: Add wrapper around fsnotify_add_event
fsnotify: Retrieve super block from the data field
fsnotify: Protect fsnotify_handle_inode_event from no-inode events

fanotify: WARN_ON against too large file handles
fanotify: Report fid info for file related file system errors
fanotify: Emit generic error info for error event
fanotify: Allow users to request FAN_FS_ERROR events
ext4: Send notifications on error
samples: Add fs error monitoring example
docs: Document the FAN_FS_ERROR event
samples: Make fs-monitor depend on libc and headers
