From d7c3f5f231c60d7e6ada5770b536df2b3ec1bd08 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Sat, 28 Oct 2006 10:38:54 -0700 Subject: [PATCH] [PATCH] fill_tgid: cleanup delays accounting fill_tgid() should skip not only an already exited group leader. If the task has ->exit_state != 0 it already did exit_notify(), so it also did fill_tgid_exit()->delayacct_add_tsk(->signal->stats) and we should skip it to avoid a double accounting. This patch doesn't close the race completely, but it cleanups the code.
