SubjectSlab corruption in fanotify_free_event()
Hi,

booting current Linus' tree (df32e43a), I am getting

Slab corruption (Not tainted): fanotify_event_info start=ffff8800372e3320, len=64

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.
