From 61010e74d76ca51dd452290d6c340c681df498ce Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 7 Feb 2014 10:29:49 -0800 Subject: rcutorture: Introduce "rcu" directory level underneath configs This commit uses the standard software ploy of introducing another level of indirection below the configs directory. This allows each torture-test suite to have its own set of Kconfig files, boot parameters, and version-specific scripts. Initially, we have only rcu, but lock will follow soonish.
