Subject: [patch 13/26] posix-timers: Rename do_schedule_next_timer
Date: Tue, 30 May 2017 23:15:46 +0200	[thread overview]
Message-ID: <20170530211656.811362578@linutronix.de> (raw)
In-Reply-To: 20170530211533.216608851@linutronix.de

[-- Attachment #1: posix-timers--Rename-do_schedule_next_timer.patch --]
[-- Type: text/plain, Size: 2977 bytes --]

That function is a misnomer. Rename it with a proper prefix to
posixtimer_rearm().
