From 0cc2441447eafd4e0742b6363e416967167c5137 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Sun, 29 Sep 2013 20:22:32 -0700 Subject: [PATCH] rcutorture: Add per-Kconfig fragment boot parameters Some Kconfig fragments require rcutorture module parameters to do optimal testing, for example, a configuration for SRCU would need rcutorture.torture_type=srcu. This commit therefore adds a per-Kconfig-fragment boot-parameter capability. Signed-off-by: Paul E.
