From db984b394ab5bd2606e117211a58f04dd635df9b Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sat, 20 Aug 2011 11:31:39 +0200 Subject: [PATCH] freezer: don't distinguish nosig tasks on thaw There's no point in thawing nosig tasks before others. There's no ordering requirement between the two groups on thaw, which the staged thawing can't guarantee anyway. Simplify thaw_processes() by removing the distinction and collapsing thaw_tasks() into thaw_processes(). This will help further updates to freezer.
