    Subject[PATCH 0/7] Profiling sleep times (v2)
    The problem is that events sched_stat_* contain call-chains of
    non-target tasks.
    About month ago I sent series of patches:

    [PATCH 0/3] trace: add ability to collect call chains of non current task.

    Peter and Frederic explained me, that this solve isn't good and will be
    better to make it in userspace.

    Now it's in userspace. This series expands "perf inject" to be able to
    merge sched_switch events and sched_stat* events. sched_switch events
    contain correct call-chains and sched_stat contains a correct time

    * Removed all known issues. Now it works completely.
    * Improved usability of sched-stat scripts according with Arun's comments.

    Andrew Vagin (7):
    perf: use event_name() to get an event name
    event: don't divide events if it has field period
    perf: add ability to record event period
    perf: add ability to change event according to sample
    perf: teach "perf inject" to work with files
    perf: teach perf inject to merge sched_stat_* and sched_switch events
    perf: add scripts for profiling sleep times
