    "content": "This series prevents a pair of data corruptions with ext4 + DAX.  The first\nsuch corruption happens when combining the inline data feature with DAX,\nand the second happens when combining data journaling with DAX.\n\nBoth can be reliably reproduced with the fstests that I have posted here:\n\nhttps://patchwork.kernel.org/patch/9948377/\nhttps://patchwork.kernel.org/patch/9948381/\n\nMy opinion is that the first three patches in this series should be applied\nto the v4.14 RC series and backported to stable.  The last two patches in\nthis series are just cleanup and can probably wait until v4.15.\n\nRoss Zwisler (5):\n  ext4: prevent data corruption with inline data + DAX\n  ext4: prevent data corruption with journaling + DAX\n  ext4: add sanity check for encryption + DAX\n  ext4: add ext4_should_use_dax()\n  ext4: remove duplicate extended attributes defs\n\n fs/ext4/ext4.h   | 37 -------------------------------------\n fs/ext4/inline.c | 10 ----------\n fs/ext4/inode.c  | 24 ++++++++++++++++--------\n fs/ext4/ioctl.c  | 16 +++++++++++++---\n fs/ext4/super.c  |  8 ++++++++\n 5 files changed, 37 insertions(+), 58 deletions(-)"
