Subject: [PATCH RESEND2 01/11] signals: kill sigfindinword()
Date: Tue, 15 Apr 2014 20:36:37 +0200 [thread overview]
Message-ID: <20140415183637.GA13389@redhat.com> (raw)
In-Reply-To: <20140415183625.GA13371@redhat.com>
It has no users and it doesn't look useful. I do not know why/when it
was introduced, I can't even find any user in the git history.
