There is one trivial hrtimer patch:


commit 8daa21e61be47a5b136c4ee1be82e391a5788696
Author: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
Date:   Thu May 28 16:21:24 2009 +0300

    hrtimer: export ktime_add_safe

    We want to use hrtimers in UBIFS (for write-buffer write-back timer).
    We need the 'hrtimer_set_expires_range_ns()', which is an in-line
    function which uses 'ktime_add_safe()'.
