DAX PMDs have been disabled since Jan Kara introduced DAX radix tree based locking. 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 from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
