Subject: [PATCH 2/7] wire up sys_time_change_notify() on ARM
Date: Tue, 31 Aug 2010 14:45:46 +0300 [thread overview]
Message-ID: <1283255151-6364-2-git-send-email-virtuoso@slind.org> (raw)
In-Reply-To: <1283255151-6364-1-git-send-email-virtuoso@slind.org>
sys_time_change_notify() is a new syscall with number and types of
parameters such that no ARM-specific processing is needed.
Tested with 2.6.36-rc3 using Documentation/time-change-notify-example.c.
