Date: Wed, 12 Dec 2007 16:10:56 -0700 From: ebiederm@...ssion.com (Eric W. Biederman) To: Ingo Molnar <mingo@...e.hu>, Thomas Gleixner <tglx@...utronix.de> Cc: Linux Containers <containers@...ts.osdl.org>, <linux-kernel@...r.kernel.org> Subject: [PATCH] Mark timer_stats as incompatible with multiple pid namespaces /proc/timer_stats currently reports the user of a timer by pid, which is a reasonable approach. However if you are not in the initial pid namespace the pid that is reported is nonsense. Therefore until we can make timer_stats pid namespace safe just disable it in the build if pid namespace support is selected so we at least know we have a conflict. Signed-off-by: Eric W.
