rcu: Test srcu_barrier() from rcutorture test suite (e3f8d378) · Commits · 戴 / test

SRCU now has a call_srcu() and an srcu_barrier(), but rcutorture does not test them. This commit adds the machinery to allow rcutorture's existing tests for call_rcu() and rcu_barrier() to apply to the SRCU equivalents. Signed-off-by:
