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/exit.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'kernel/exit.c') diff --git a/kernel/exit.c b/kernel/exit.c index 601263c0806..819d82c2efb 100644 --- a/kernel/exit.c +++ b/kernel/exit.c @@ -894,7 +894,7 @@ fastcall NORET_TYPE void do_exit(long code) if (group_dead) { hrtimer_cancel(&tsk->signal->real_timer); exit_itimers(tsk->signal); - acct_process(code); + acct_collect(); } if (unlikely(tsk->robust_list)) exit_robust_list(tsk); @@ -906,6 +906,8 @@ fastcall NORET_TYPE void do_exit(long code) audit_free(tsk); exit_mm(tsk); + if (group_dead) + acct_process(code); exit_sem(tsk); __exit_files(tsk); __exit_fs(tsk); -- cgit v1.2.3
