Subject: [PATCH 3/5] RT - fix mistargeted RESCHED_IPI
Date: Tue, 09 Oct 2007 10:25:59 -0400 [thread overview]
Message-ID: <20071009142559.4941.60009.stgit@novell1.haskins.net> (raw)
In-Reply-To: <20071009142044.4941.65189.stgit@novell1.haskins.net>
Any number of tasks could be queued behind the current task, so direct the
balance IPI at all CPUs (other than current)
