Subject: [PATCH tip/core/rcu 12/28] rcutorture: Adjust scenarios SRCU-t and SRCU-u to make kconfig happy
From: "Paul E. McKenney" <paulmck@...nel.org>
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. McKenney <paulmck@...nel.org>
