Hello Linus,
could you please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs.git fsnotify_for_v5.9-rc1
This pull contains:
* fanotify fix for softlockups when there are many queued events
* performance improvement to reduce fsnotify overhead when not used
* Amir's implementation of fanotify events with names
With Amir's patches you can now efficiently monitor whole filesystem and
say mirror changes to another machine.
Top of the tree is 8aed8cebdd97. The full shortlog is:
Amir Goldstein (34):
fsnotify: fold fsnotify() call into fsnotify_parent()
fsnotify: return non const from fsnotify_data_inode()
nfsd: use fsnotify_data_inode() to get the unlinked inode
kernfs: do not call fsnotify() with name without a parent
inotify: do not use objectid when comparing events
fanotify: create overflow event type
fanotify: break up fanotify_alloc_event()
fsnotify: pass dir argument to handle_event() callback
fanotify: remove event FAN_DIR_MODIFY
fanotify: generalize the handling of extra event flags
fanotify: generalize merge logic of events on dir
fanotify: distinguish between fid encode error and null fid
fanotify: generalize test for FAN_REPORT_FID
fanotify: mask out special event flags from ignored mask
fanotify: prepare for implicit event flags in mark mask
fanotify: use FAN_EVENT_ON_CHILD as implicit flag on sb/mount/non-dir marks
fsnotify: add object type "child" to object type iterator
fanotify: use struct fanotify_info to parcel the variable size buffer
fanotify: no external fh buffer in fanotify_name_event
dnotify: report both events on parent and child with single callback
inotify: report both events on parent and child with single callback
fsnotify: send event to parent and child with single callback
fsnotify: create helper fsnotify_inode()
fsnotify: pass dir and inode arguments to fsnotify()
inotify: do not set FS_EVENT_ON_CHILD in non-dir mark mask
audit: do not set FS_EVENT_ON_CHILD in audit marks mask
fsnotify: send event with parent/name info to sb/mount/non-dir marks
fsnotify: remove check that source dentry is positive
fanotify: add basic support for FAN_REPORT_DIR_FID
fanotify: report events with parent dir fid to sb/mount/non-dir marks
fanotify: add support for FAN_REPORT_NAME
fanotify: report parent fid + name + child fid
fanotify: report parent fid + child fid
fsnotify: create method handle_inode_event() in fsnotify_operations
Jan Kara (2):
fanotify: Avoid softlockups when reading many events
fanotify: compare fsid when merging name event
Mel Gorman (1):
fsnotify: Rearrange fast path to minimise overhead when there is no watcher
