Subject: [PATCH 2/4] printk: Rename printk_sched to printk_deferred
Date: Mon,  5 May 2014 13:47:42 -0700	[thread overview]
Message-ID: <1399322864-22861-3-git-send-email-john.stultz@linaro.org> (raw)
In-Reply-To: <1399322864-22861-1-git-send-email-john.stultz@linaro.org>

After learning we'll need some sort of deferred printk functionality
in the timekeeping core, Peter suggested we rename the printk_sched
function so it can be reused by needed subsystems.

This only changes the function name. No logic changes.
