Subject: inotify: fix check for one-shot watches before destroying them
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ac74c00e499ed276a965e5b5600667d5dc04a84a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

inotify: fix check for one-shot watches before destroying them

As the IN_ONESHOT bit is never set when an event is sent we must check it
in the watch's mask and not in the event's mask.
