Pull fsnotify updates from Jan Kara:
"fsnotify cleanups from Amir and a small inotify improvement"
* tag 'fsnotify_for_v4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
inotify: Add flag IN_MASK_CREATE for inotify_add_watch()
fanotify: factor out helpers to add/remove mark
fsnotify: add helper to get mask from connector
fsnotify: let connector point to an abstract object
fsnotify: pass connp and object type to fsnotify_add_mark()
fsnotify: use typedef fsnotify_connp_t for brevity
