Hi,

sys_membarrier has been merged into Linux 4.3-rc1. It can therefore
be tested on top of Linus' master by applying this patch.

Successfully tested with todays Linus' master, membarrier_test has passed.
Patch applied to linux-s390 but with a different system call number.
#355 is already taken by sys_userfaultfd, the new one for membarrier is #356.
