Thanks. I get: $ ./membarrier_test membarrier MEMBARRIER_CMD_QUERY syscall available. membarrier: MEMBARRIER_CMD_SHARED success. membarrier: tests done! Which looks good. Assuming the membarrier support hits 4.3, I'll take this via my tree for 4.3 also. cheers _______________________________________________ Linuxppc-dev mailing list [email protected] https://lists.ozlabs.org/listinfo/linuxppc-dev
