Message-ID: <20090615185638.GK21741@gandalf.sssup.it> Date: Mon, 15 Jun 2009 20:56:38 +0200 From: Fabio Checconi <fchecconi@...il.com> To: mingo@...e.hu, a.p.zijlstra@...llo.nl Cc: linux-kernel@...r.kernel.org Subject: [PATCH 1/8] Fix rt_rq->pushable_tasks initialization in init_rt_rq() init_rt_rq() initializes only rq->rt.pushable_tasks, and not the pushable_tasks field of the passed rt_rq. The plist is not used uninitialized since the only pushable_tasks plists used are the ones of root rt_rqs; anyway reinitializing the list on every group creation corrupts the root plist, losing its previous contents.
