Subject: [PATCH tip/core/rcu 12/26] x86: Use the new schedule_user API on userspace preemption
Date: Thu, 30 Aug 2012 14:05:29 -0700 [thread overview]
Message-ID: <1346360743-3628-12-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <1346360743-3628-1-git-send-email-paulmck@linux.vnet.ibm.com>
From: Frederic Weisbecker <fweisbec@gmail.com>
This way we can exit the RCU extended quiescent state before
we schedule a new task from irq/exception exit.
