From 492b95e59735998312f678d77a2d5fe20af6b0b9 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com> Date: Fri, 21 Apr 2017 16:09:15 -0700 Subject: [PATCH] rcuperf: Set more user-friendly defaults Common-case use of rcuperf must set rcuperf.nreaders=0 and if not built as a module, rcuperf.shutdown. This commit therefore sets the default for rcuperf.nreaders to zero and sets the default for rcuperf.shutdown to zero if rcuperf is built as a module and to one otherwise. Signed-off-by: Paul E.
