These patches are rebased against Linus tree. The 203b42f7317494ae5e5efc7be6fb7f29c927f102 commit, which renames INIT_DELAYED_WORK_DEFERRABLE to INIT_DEFERRABLE_WORK could be the reason for patchset not applying over 3.6. > > >> >> Changes since v1: >> - revised locking mechanism >> - added kerneldoc comments for load monitoring helper functions >> - fixed minor review comments >> >> Changes since v2: >> - added new helper function for polling interval update >> - handled work suspend/resume contention between devfreq driver >> and sysfs >> >> Changes since v3: >> - added additonal checks in suspend/resume to avoid invalid usage of apis >> - added check in devfreq_monitor_start, not to start monitoring when >> polling_ms is set to zero. >> >> -- >> Rajagopal Venkat (3): >> devfreq: Core updates to support devices which can idle >> devfreq: Add suspend and resume apis >> devfreq: Add current freq callback in device profile >> >> Documentation/ABI/testing/sysfs-class-devfreq | 15 +- >> drivers/devfreq/devfreq.c | 481 >> ++++++++++++-------------- >> drivers/devfreq/governor.h | 13 + >> drivers/devfreq/governor_performance.c | 16 +- >> drivers/devfreq/governor_powersave.c | 16 +- >> drivers/devfreq/governor_simpleondemand.c | 33 ++ >> drivers/devfreq/governor_userspace.c | 23 +- >> include/linux/devfreq.h | 49 +-- >> 8 files changed, 353 insertions(+), 293 deletions(-) >> >> -- >> 1.7.11.3 >> >> >> >> >> >> >> >> -- Regards, Rajagopal -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
