Subject: [PATCH 03/14] prctl.2: tfix mis-description of thread ID values in procfs
Date: Tue, 12 May 2020 17:36:48 +0100	[thread overview]
Message-ID: <1589301419-24459-4-git-send-email-Dave.Martin@arm.com> (raw)
In-Reply-To: <1589301419-24459-1-git-send-email-Dave.Martin@arm.com>

Under PR_SET_NAME, the [tid] value seen in procfs as
/proc/self/task/[tid] is mistakenly described as the name of the
thread, whereas really the name is on /proc/self/task/[tid]/comm.

Fix it.
