From 9fcc2d15b14894aa53e5e8b7fd5d6e3ca558e5df Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 14 Nov 2007 17:00:07 -0800 Subject: [PATCH] proc: simplify and correct proc_flush_task Currently we special case when we have only the initial pid namespace. Unfortunately in doing so the copied case for the other namespaces was broken so we don't properly flush the thread directories :( So this patch removes the unnecessary special case (removing a usage of proc_mnt) and corrects the flushing of the thread directories.
