Subject: [PATCH 0/2] time: Fix races at clocksource switch time
Date: Wed, 14 Mar 2012 16:58:54 -0700 [thread overview]
Message-ID: <1331769536-4602-1-git-send-email-john.stultz@linaro.org> (raw)
In testing some recent timekeeping changes, I found some problem
when changing clocksources.
These two patches close races at clocksource switch time. One I sent out
earlier, and have reworked to integrate Thomas' comments.
These two patches, along with Thomas' recent cleanup patches ontop can
be found here:
