Hi, I am submitting the membarrier system call for the upcoming Linux 4.2 merge window. It would be nice if it could sit a few days in Andrew Morton's tree before that.
A major addition to sys_membarrier changelog is the inclusion of the list of users which would benefit from having this system call today. Thanks, Mathieu Mathieu Desnoyers (2): sys_membarrier(): system-wide memory barrier (generic, x86) (v19) selftests: enhance membarrier syscall test Pranith Kumar (1): selftests: add membarrier syscall test MAINTAINERS | 8 ++ arch/x86/syscalls/syscall_32.tbl | 1 + arch/x86/syscalls/syscall_64.tbl | 1 + include/linux/syscalls.h | 2 + include/uapi/asm-generic/unistd.h | 4 +- include/uapi/linux/Kbuild | 1 + include/uapi/linux/membarrier.h | 53 +++++++++ init/Kconfig | 12 ++ kernel/Makefile | 1 + kernel/membarrier.c | 66 +++++++++++ kernel/sys_ni.c | 3 + tools/testing/selftests/Makefile | 1 + tools/testing/selftests/membarrier/.gitignore | 1 + tools/testing/selftests/membarrier/Makefile | 11 ++ .../testing/selftests/membarrier/membarrier_test.c | 121 +++++++++++++++++++++ 15 files changed, 285 insertions(+), 1 deletion(-) create mode 100644 include/uapi/linux/membarrier.h create mode 100644 kernel/membarrier.c create mode 100644 tools/testing/selftests/membarrier/.gitignore create mode 100644 tools/testing/selftests/membarrier/Makefile create mode 100644 tools/testing/selftests/membarrier/membarrier_test.c -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
