tools/memory-model: Add smp_mb__after_srcu_read_unlock()
This commit adds support for smp_mb__after_srcu_read_unlock(), which,
when combined with a prior srcu_read_unlock(), implies a full memory
barrier. No ordering is guaranteed to accesses between the two, and
placing accesses between is bad practice in any case.
Tests may be found at https://github.com/paulmckrcu/litmus in files
matching manual/kernel/C-srcu-mb-*.litmus.
