McKenney Date: Thu Sep 17 12:34:01 2020 -0700 rcutorture: Adjust scenarios SRCU-t and SRCU-u to make kconfig happy The SRCU-u scenario expects to enable lockdep but to also disable the CONFIG_PREEMPT_COUNT kconfig option. This no longer works. This commit therefore instead enables lockdep in SRCU-t, which then allows SRCU-u to disable CONFIG_PREEMPT_COUNT. Signed-off-by: Paul E.
