The patch titled Subject: signal: oom_kill_task: use SEND_SIG_FORCED instead of force_sig() has been removed from the -mm tree. Its filename was signal-oom_kill_task-use-send_sig_forced-instead-of-force_sig.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ From: Oleg Nesterov <oleg@xxxxxxxxxx> Subject: signal: oom_kill_task: use SEND_SIG_FORCED instead of force_sig() Change oom_kill_task() to use do_send_sig_info(SEND_SIG_FORCED) instead of force_sig(SIGKILL). With the recent changes we do not need force_ to kill the CLONE_NEWPID tasks. And this is more correct. force_sig() can race with the exiting thread even if oom_kill_task() checks p->mm != NULL, while do_send_sig_info(group => true) kille the whole process.
