[PATCH 1/3] exit: always reap resource stats in __exit_signal

2014-08-15 Thread riel
From: Rik van Riel Oleg pointed out that wait_task_zombie adds a task's usage statistics to the parent's signal struct, but the task's own signal struct should also propagate the statistics at exit time. This allows thread_group_cputime(reaped_zombie) to get the statistics after

[PATCH 3/3] sched,time: atomically increment stime & utime

2014-08-15 Thread riel
From: Rik van Riel The functions task_cputime_adjusted and thread_group_cputime_adjusted can be called locklessly, as well as concurrently on many different CPUs. This can occasionally lead to the utime and stime reported by times(), and other syscalls like it, going backward. The cause for

[PATCH 2/3] time,signal: protect resource use statistics with seqlock

2014-08-15 Thread riel
From: Rik van Riel Both times() and clock_gettime(CLOCK_PROCESS_CPUTIME_ID) have scalability issues on large systems, due to both functions being serialized with a lock. The lock protects against reporting a wrong value, due to a thread in the task group exiting, its statistics reporting up to
