266 For example, use of smp_store_release() saves a line compared to the

272 More important, smp_store_release() makes it easier to connect up the

286 smp_store_release(), which still provides the needed ordering of "x"
287 against "y". On x86, the version using smp_store_release() might compile
295 smp_store_release(), but also atomic_set_release(), and
299 smp_store_release() except that: (1) It takes the pointer to
