Andrew, This contains both my DAX tracepoint code and Dave Jiang's MM argument simplifications. Dave's code was written with my tracepoint code as a baseline, so it seemed simplest to keep them together in a single series. This series is based on the v4.10-rc3-mmots-2017-01-09-17-08 snapshot. A working tree can be found here: https://git.kernel.org/cgit/linux/kernel/git/zwisler/linux.git/log/?h=mmots_dax_tracepoint Changes from the previous versions of these patches: - Combined Dave's code and mine into a single series. - Resolved some minor merge conflics in Dave's patches so they could be applied to the latest mmots snapshot. - Added Reviewed-by and Acked-by tags to patches as appropriate. My goal for this series is to get it merged for v4.11. Thanks, - Ross Dave Jiang (2): mm, dax: make pmd_fault() and friends to be the same as fault() mm, dax: move pmd_fault() to take only vmf parameter Ross Zwisler (5): tracing: add __print_flags_u64() dax: add tracepoint infrastructure, PMD tracing dax: update MAINTAINERS entries for FS DAX dax: add tracepoints to dax_pmd_load_hole() dax: add tracepoints to dax_pmd_insert_mapping() MAINTAINERS | 5 +- drivers/dax/dax.c | 26 ++++--- fs/dax.c | 114 ++++++++++++++++-------------- fs/ext4/file.c | 13 ++-- fs/xfs/xfs_file.c | 15 ++-- include/linux/dax.h | 6 +- include/linux/mm.h | 28 +++++++- include/linux/pfn_t.h | 6 ++ include/linux/trace_events.h | 4 ++ include/trace/events/fs_dax.h | 156 ++++++++++++++++++++++++++++++++++++++++++ include/trace/trace_events.h | 11 +++ kernel/trace/trace_output.c | 38 ++++++++++ mm/memory.c | 11 ++- 13 files changed, 338 insertions(+), 95 deletions(-) create mode 100644 include/trace/events/fs_dax.h -- 2.7.4 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
