From 86174cdcb44c095ffd2e3ca69caa56244cf701d5 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Sun, 8 Jan 2006 01:03:28 -0800 Subject: [PATCH] [PATCH] remove unneeded sig->curr_target recalculation This patch removes unneeded sig->curr_target recalculation under 'if (atomic_dec_and_test(&sig->count))' in __exit_signal(). When sig->count == 0 the signal can't be sent to this task and next_thread(tsk) == tsk anyway.
