2015-09-11selftests: enhance membarrier syscall testMathieu Desnoyers1-25/+75
Update the membarrier syscall self-test to match the membarrier interface. Extend coverage of the interface. Consider ENOSYS as a "SKIP" test, since it is a valid configuration, but does not allow testing the system call.
