Merge tag 'for_v4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Pull fsnotify updates from Jan Kara:
 "Amir's patches to implement superblock fanotify watches, Xiaoming's
  patch to enable reporting of thread IDs in fanotify events instead of
  TGIDs (sadly the patch got mis-attributed to Amir and I've noticed
  only now), and a fix of possible oops on umount caused by fsnotify
  infrastructure"
