Merge tag 'fsnotify_for_v4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
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
