Subject: [PATCH v5 0/8] posix timers fixlet

From: KOSAKI Motohiro <kosaki.motohiro@...fujitsu.com>

Glibc's posix timer testcase found a lot of bugs in posix timer code.
This series, hopefully, fixes all of them. All patches are independent 
each other logically.

Changes from v4
 - [1/8] comments colarification, fix account_group_{user_system}_time too.
 - [8/8] added CPUCLOCK_VIRT and CPUCLOCK_PROF timer initialization fix

Changes from v3
 - task_sched_runtime() micro optimization add to care tsk->on_cpu.
   suggested Paul Turner.
 - fixed several typo in changelogs.


KOSAKI Motohiro (8):
  posix-cpu-timers: don't account cpu timer after stopped thread
    runtime accounting
  posix-cpu-timers: fix acounting delta_exec twice
  posix-cpu-timers: fix wrong timer initialization
  posix-cpu-timers: timer functions should use timer time instead of
    clock time
  posix-cpu-timers: check_thread_timers() uses task_sched_runtime()
  sched: task_sched_runtime introduce micro optimization
  posix-cpu-timers: cleanup cpu_{clock,timer}_sample{,_group}
  posix-cpu-timers: fix cputimer initialization mistake for {u,s}time
