From ccd60ad3f87f6a5f2974a7f206e77b49b251e94c Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 22 Apr 2015 07:20:51 -0700 Subject: [PATCH] rcutorture: Update TREE_RCU-kconfig.txt This commit updates TREE_RCU-kconfig.txt to reflect changes in RCU's Kconfig setup. This commit also updates rcutorture's Kconfig fragments to account for Kconfig parameters that are now driven directly off of other Kconfig parameters. The #CHECK# prefix tells the rcutorture scripts to take no action to try to set the Kconfig parameter, but to check that it does in fact get set. This is useful for verifying that Kconfig parameters that are supposed to be automatically set do in fact get set to the required values. Reported-by: Pranith Kumar Signed-off-by: Paul E.
