Date: Thu, 12 Mar 2015 18:08:57 -0400 From: Steven Rostedt <rostedt@...dmis.org> To: LKML <linux-kernel@...r.kernel.org>, linux-rt-users <linux-rt-users@...r.kernel.org> Cc: Thomas Gleixner <tglx@...utronix.de>, Sebastian Andrzej Siewior <bigeasy@...utronix.de> Subject: [PATCH RT] irq_work: Hide access to hirq_work_list in PREEMPT_RT_FULL The hirq_work_list is only defined when PREEMPT_RT_FULL is configured. Most access to it is within an #ifdef CONFIG_PREEMPT_RT_FULL, except for one. Encapsulate that location too.
