Subject: [PATCH 01/22] fsnotify: Remove unnecessary tests when showing fdinfo
Date: Fri, 20 Jan 2017 14:21:02 +0100 [thread overview]
Message-ID: <20170120132123.9670-2-jack@suse.cz> (raw)
In-Reply-To: <20170120132123.9670-1-jack@suse.cz>
show_fdinfo() iterates group's list of marks. All marks found there are
guaranteed to be alive and they stay so until we release
group->mark_mutex. So remove uncecessary tests whether mark is alive.
