From fa717060f1ab7eb6570f2fb49136f838fc9195a9 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Fri, 25 Jan 2008 21:08:27 +0100 Subject: sched: sched_rt_entity Move the task_struct members specific to rt scheduling together. A future optimization could be to put sched_entity and sched_rt_entity into a union.
