From 29766f1eb3d8d6cfaf1d6623fb4c3f7e5a822fe4 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 27 Jun 2006 02:54:02 -0700 Subject: [PATCH] [PATCH] rcutorture: catchup doc fixes for idle-hz tests This just catches the RCU torture documentation up with the recent fixes that test RCU for architectures that turn of the scheduling-clock interrupt for idle CPUs and the addition of a SUCCESS/FAILURE indication, fixing up an obsolete comment as well.
