From 266b7a021f7dcc4d4531961a47f4ef74c3c4ab6b Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Wed, 3 Jul 2013 15:08:35 -0700 Subject: [PATCH] fs/exec.c:de_thread: mt-exec should update ->real_start_time 924b42d5 ("Use boot based time for process start time and boot time in /proc") updated copy_process/do_task_stat but forgot about de_thread(). This breaks "ps axOT" if a sub-thread execs. Note: I think that task->start_time should die. Signed-off-by: Oleg Nesterov Cc: "Eric W.
