    ext2: Add alignment check for DAX mount · 284854be
    Toshi Kani authored
    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.
    
    Call bdev_dax_supported() to perform proper precondition checks
    which includes this partition alignment check.
