From e5f9c93d5ceadd86ab16520d3faadb3c4a032a8f Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 31 Oct 2011 15:30:30 -0700 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.
