Subject: make do_notify_parent() __must_check, update the callers
X-Git-Tag: v3.1-rc1~308^2~15
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8677347378044ab564470bced2275520efb3670d;p=pandora-kernel.git

make do_notify_parent() __must_check, update the callers

Change other callers of do_notify_parent() to check the value it
returns, this makes the subsequent task_detached() unnecessary.
Mark do_notify_parent() as __must_check.

Use thread_group_leader() instead of !task_detached() to check
if we need to notify the real parent in wait_task_zombie().

Remove the stale comment in release_task(). "just for sanity" is
no longer true, we have to set EXIT_DEAD to avoid the races with
do_wait().
