I guess this is due to
commit 7053aee26a3548ebaba046ae2e52396ccf56ac6c Author: Jan Kara <jack@suse.cz> Date: Tue Jan 21 15:48:14 2014 -0800
fsnotify: do not share events between notification groups
as I am not able to see any other recent changes in that area. Haven't been looking at the patch closely enough to debug this yet ... sending this as an early heads-up.
