Subject: [patch 03/13] delayacct: Use ktime_get_ts()
Date: Wed, 11 Jun 2014 23:59:13 -0000	[thread overview]
Message-ID: <20140611234606.931409215@linutronix.de> (raw)
In-Reply-To: 20140611234024.103571777@linutronix.de

[-- Attachment #1: kernel-delayacct-use-ktime-get.patch --]
[-- Type: text/plain, Size: 1599 bytes --]

do_posix_clock_monotonic_gettime() is a leftover from the initial
posix timer implementation which maps to ktime_get_ts(). Remove the
silly wrapper while at it.
