This series allows DAX PMDs to participate in the DAX radix tree based locking scheme so that they can be re-enabled. Changes since v7: - Rebased on v4.9-rc1, dropping one ext4 patch that had already been merged. - Added Reviewed-by tags from Jan Kara. Here is a tree containing my changes: https://git.kernel.org/cgit/linux/kernel/git/zwisler/linux.git/log/?h=dax_pmd_v8 Ross Zwisler (16): ext4: tell DAX the size of allocation holes dax: remove buffer_size_valid() ext2: remove support for DAX PMD faults dax: make 'wait_table' global variable static dax: remove the last BUG_ON() from fs/dax.c dax: consistent variable naming for DAX entries dax: coordinate locking for offsets in PMD range dax: remove dax_pmd_fault() dax: correct dax iomap code namespace dax: add dax_iomap_sector() helper function dax: dax_iomap_fault() needs to call iomap_end() dax: move RADIX_DAX_* defines to dax.h dax: move put_(un)locked_mapping_entry() in dax.c dax: add struct iomap based DAX PMD support xfs: use struct iomap based DAX PMD fault path dax: remove "depends on BROKEN" from FS_DAX_PMD fs/Kconfig | 1 - fs/dax.c | 826 +++++++++++++++++++++++++++++----------------------- fs/ext2/file.c | 35 +-- fs/ext4/inode.c | 3 + fs/xfs/xfs_aops.c | 26 +- fs/xfs/xfs_aops.h | 3 - fs/xfs/xfs_file.c | 10 +- include/linux/dax.h | 58 +++- mm/filemap.c | 5 +- 9 files changed, 537 insertions(+), 430 deletions(-) -- 2.7.4 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
