Subject: [REVIEW][PATCH 3/4] proc: Point /proc/net at /proc/thread-self/net instead of /proc/self/net
Date: Thu, 31 Jul 2014 17:34:32 -0700	[thread overview]
Message-ID: <8761idcajr.fsf@x220.int.ebiederm.org> (raw)
In-Reply-To: <87oaw5caq1.fsf-JOvCrm2gF+uungPnsOpG7nhyD016LWXt@public.gmane.org> (Eric W. Biederman's message of "Thu, 31 Jul 2014 17:30:46 -0700")


In oddball cases where the thread has a different network namespace
than the primary thread group leader or more likely in cases where
the thread remains and the thread group leader has exited this
ensures that /proc/net continues to work.

This should not cause any problems but if it does this patch can just
be reverted.
