From c09c144139f227de13330111adcafa1659ebd008 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Fri, 6 Jun 2014 14:36:50 -0700 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.
