Also the previous pull request lacked a high level overall description, so I'm adding one here. --- Posix cpu timers changes for 3.14: * Remove dying thread/process timers caching that were complicating the code for no significant win. * Remove early task reference release on dying timer sample read. Again it was not worth the code complication. The other timer's resources aren't released until timer_delete() is called anyway (or when the whole process dies). * Remove leftover arguments in reaped target cleanup * Consolidate some timer sampling code * Remove use of tasklist lock * Robustify sighand locking against exec and exit by using the safer lock_task_sighand() API instead of sighand raw locking. * Convert some unnecessary BUG_ON() to WARN_ON() Thanks, Frederic --- Frederic Weisbecker (10): posix-timers: Remove dead thread posix cpu timers caching posix-timers: Remove dead process posix cpu timers caching posix-timers: Cleanup reaped target handling posix-timers: Remove dead task special case posix-timers: Remove useless clock sample on timers cleanup posix-timers: Consolidate posix_cpu_clock_get() posix-timers: Use sighand lock instead of tasklist_lock for task clock sample posix-timers: Use sighand lock instead of tasklist_lock on timer deletion posix-timers: Remove remaining uses of tasklist_lock posix-timers: Convert abuses of BUG_ON to WARN_ON kernel/posix-cpu-timers.c | 312 +++++++++++++++++++--------------------------- 1 file changed, 129 insertions(+), 183 deletions(-)
