From 0e4648141af02331f21aabcd34940c70f09a2d04 Mon Sep 17 00:00:00 2001 From: KaiGai Kohei Date: Sun, 25 Jun 2006 05:49:24 -0700 Subject: [PATCH] pacct: add pacct_struct to fix some pacct bugs. The pacct facility need an i/o operation when an accounting record is generated. There is a possibility to wake OOM killer up. If OOM killer is activated, it kills some processes to make them release process memory regions. But acct_process() is called in the killed processes context before calling exit_mm(), so those processes cannot release own memory. In the results, any processes stop in this point and it finally cause a system stall. --- kernel/fork.c | 1 + 1 file changed, 1 insertion(+) (limited to 'kernel/fork.c') diff --git a/kernel/fork.c b/kernel/fork.c index 49adc0e8d47c..dfd10cb370c3 100644 --- a/kernel/fork.c +++ b/kernel/fork.c @@ -874,6 +874,7 @@ static inline int copy_signal(unsigned long clone_flags, struct task_struct * ts tsk->it_prof_expires = secs_to_cputime(sig->rlim[RLIMIT_CPU].rlim_cur); } + acct_init_pacct(&sig->pacct); return 0; } -- cgit v1.2.3
