From: Oleg Nesterov Date: Wed, 30 Apr 2008 07:52:48 +0000 (-0700) Subject: signals: send_sigqueue: don't forget about handle_stop_signal() X-Git-Tag: v2.6.26-rc1~296 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=5fc894bb4fb1de8373d1d5fb6db19204a16859e8;p=linux-2.6-omap-h63xx.git signals: send_sigqueue: don't forget about handle_stop_signal() send_group_sigqueue() calls handle_stop_signal(), send_sigqueue() doesn't. This is not consistent and in fact I'd say this is (minor) bug. Move handle_stop_signal() from send_group_sigqueue() to do_send_sigqueue(), the latter is called by send_sigqueue() too.
