Subject[PATCH v2 0/3] Add alignment check for DAX mount
Date
When a partition is not aligned by 4KB, mount -o dax succeeds,
but any read/write access to the filesystem fails, except for
metadata update.

Add alignment check to ext4, ext2, and xfs.

v2:
- Use a helper function via ->direct_access for the check.
(Christoph Hellwig)
- Call bdev_direct_access() with sector 0 for the check.
(Boaz Harrosh)
