Subject: [PATCH 0/5] Introduce CLOCK_BOOTTIME
Date: Tue, 15 Feb 2011 20:20:02 -0800	[thread overview]
Message-ID: <1297830007-426-1-git-send-email-john.stultz@linaro.org> (raw)

This patch set (applies against tip/timers/core) extends the
hrtimer, timekeeping, and posix-timer code to support a new 
clockid: CLOCK_BOOTTIME.

CLOCK_BOOTTIME is identical to CLOCK_MONOTONIC, except it also
includes any time spent in suspend (as currently measured by
read_persistent_clock()). This allows applications to get a
suspend aware monotonic clock.

Thomas, I've included your suggestions from the last round.
Does this look like something you could queue for 2.6.39?

thanks
-john

John Stultz (5):
  hrtimers: extend hrtimer base code to handle more then 2 clockids
  time: Introduce get_monotonic_boottime and ktime_get_boottime
  time: Extend get_xtime_and_monotonic_offset() to also return sleep
  timers: Add CLOCK_BOOTTIME hrtimer base
  timers: Export CLOCK_BOOTTIME via the posix timers interface
