Subject: wait_task_zombie plus WNOWAIT question
Date: Wed, 01 Jul 2009 15:41:02 +0200 [thread overview]
Message-ID: <87eit0h66p.wl%vmayatsk@redhat.com> (raw)
Hi!
I'm working on (sigh) next version of wait_task_* cleanups and stuck
in wait_task_zombie. I'm trying to move put_user(stat, wo->wo_stat)
code from all wait_task_* functions to common place, but
wait_task_zombie does not fill wo_stat if WNOWAIT flag is set and does
it w/o that flag. Is it done so by design, or I can make
user-visible change and add put_user in WNOWAIT path?
Thanks!
