From e746b558572efbad250e35e582a32ecabc9e9316 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Sat, 7 Jul 2018 17:35:22 -0700 Subject: rcutorture: Warn on bad torture type for built-in tests When running a built-in rcutorture test, specifying an invalid torture type results in what looks like a hard hang, with the error messages hidden by other boot-time output. This commit therefore executes a WARN_ON() in this case so that the splat appears just following the error messages. Signed-off-by: Paul E.
