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 v3
- task_sched_runtime() micro optimization add to care tsk->on_cpu.
suggested Paul Turner.
- fixed several typo in changelogs.
KOSAKI Motohiro (7):
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}
