oom: oom_forkbomb_penalty: move thread_group_cputime() out of task_lock()
On Fri, 2 Apr 2010, Oleg Nesterov wrote: It doesn't make sense to call thread_group_cputime() under task_lock(), we can drop this lock right after we read get_mm_rss() and save the value in the local variable. Note: probably it makes more sense to use sum_exec_runtime instead of utime + stime, it i... 2 Apr 2010 15:57

[PATCH -mm 3/4] oom: introduce find_lock_task_mm() to fix !mm false positives
Almost all ->mm == NUL checks in oom_kill.c are wrong. The current code assumes that the task without ->mm has already released its memory and ignores the process. However this is not necessarily true when this process is multithreaded, other live sub-threads can use this ->mm. - Remove the "if (!p->mm)" check... 2 Apr 2010 14:50
