The patch titled
     Subject: signals: rename rm_from_queue_full() to flush_sigqueue_mask()
has been removed from the -mm tree.  Its filename was
     signals-rename-rm_from_queue_full-to-flush_sigqueue_mask.patch

This patch was dropped because it was merged into mainline or a subsystem tree

From: Oleg Nesterov <oleg@redhat.com>
Subject: signals: rename rm_from_queue_full() to flush_sigqueue_mask()

"rm_from_queue_full" looks ugly and misleading, especially now that
rm_from_queue() has gone away.  Rename it to flush_sigqueue_mask(), this
matches flush_sigqueue() we already have.

Also remove the obsolete comment which explains the difference with
rm_from_queue() we already killed.
