From cc1321c96f855525fbd847fec130f000daa1bb1f Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 16 Oct 2017 11:05:03 -0700 Subject: torture: Reduce #ifdefs for preempt_schedule() This commit adds a torture_preempt_schedule() that is nothingness in !PREEMPT builds and is preempt_schedule() otherwise. Then torture_preempt_schedule() is used to eliminate several ugly #ifdefs, both in rcutorture and in locktorture. Signed-off-by: Paul E.
