Subject: fanotify: quit wanking with FASYNC in ->release()
X-Git-Tag: v3.11-rc1~124^2~41
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=3058dca6945f12f1777eb40d43f4c97351a9c175;p=linux.git

fanotify: quit wanking with FASYNC in ->release()

... especially since there's no way to get that sucker
on the list fsnotify_fasync() works with - the only thing
adding to it is fsnotify_fasync() itself and it's never
called for fanotify files while they are opened.
