The patch titled
signals: send_sigqueue: don't forget about handle_stop_signal()
has been removed from the -mm tree. Its filename was
signals-send_sigqueue-dont-forget-about-handle_stop_signal.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: signals: send_sigqueue: don't forget about handle_stop_signal()
From: Oleg Nesterov <oleg@xxxxxxxxxx>
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.
