In this iteration, following Joe Perches's suggestion, I've extracted kmsg related functions from printk.c to a new file, kmsg.c. Best regards, Paul Marcin Niesluchowski (7): printk: add one function for storing log in proper format kmsg: introduce additional kmsg devices support kmsg: add additional buffers support to memory class kmsg: add function for adding and deleting additional buffers kmsg: add ioctl for adding and deleting kmsg* devices kmsg: add ioctl for kmsg* devices operating on buffers kmsg: add predefined _PID, _TID, _COMM keywords to kmsg* log dict Paul Osmialowski (2): printk: extract kmsg-related routines from printk.c to kmsg.c kmsg: selftests Documentation/ioctl/ioctl-number.txt | 1 + drivers/char/mem.c | 27 +- fs/proc/kmsg.c | 4 +- include/linux/printk.h | 48 + include/uapi/linux/Kbuild | 1 + include/uapi/linux/kmsg_ioctl.h | 45 + kernel/printk/Makefile | 1 + kernel/printk/kmsg.c | 1054 +++++++++++++++++ kernel/printk/printk.c | 1250 +++++--------------- kernel/printk/printk.h | 247 ++++ samples/kmsg/kmsg-api.h | 44 + tools/testing/selftests/Makefile | 1 + tools/testing/selftests/kmsg/.gitignore | 1 + tools/testing/selftests/kmsg/Makefile | 30 + tools/testing/selftests/kmsg/kmsg-test.c | 329 ++++++ tools/testing/selftests/kmsg/kmsg-test.h | 34 + tools/testing/selftests/kmsg/test-buffer-add-del.c | 76 ++ .../kmsg/test-buffer-add-write-read-del.c | 161 +++ .../kmsg/test-buffer-buf-multithreaded-torture.c | 199 ++++ .../selftests/kmsg/test-buffer-buf-torture.c | 139 +++ 20 files changed, 2729 insertions(+), 963 deletions(-) create mode 100644 include/uapi/linux/kmsg_ioctl.h create mode 100644 kernel/printk/kmsg.c create mode 100644 kernel/printk/printk.h create mode 100644 samples/kmsg/kmsg-api.h create mode 100644 tools/testing/selftests/kmsg/.gitignore create mode 100644 tools/testing/selftests/kmsg/Makefile create mode 100644 tools/testing/selftests/kmsg/kmsg-test.c create mode 100644 tools/testing/selftests/kmsg/kmsg-test.h create mode 100644 tools/testing/selftests/kmsg/test-buffer-add-del.c create mode 100644 tools/testing/selftests/kmsg/test-buffer-add-write-read-del.c create mode 100644 tools/testing/selftests/kmsg/test-buffer-buf-multithreaded-torture.c create mode 100644 tools/testing/selftests/kmsg/test-buffer-buf-torture.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
