Re: [PATCH v3 4/5] ext2: Add alignment check for DAX mount

[Christoph Hellwig]

Not really for the patch, but given that we have the right people
on CC:

Do we really want to keep DAX support in ext2 in the long run?  ext2
is missing a lot of the useful features for a modern FS, shouldn't
we direct people to use ext4 (in non-journal mode if needed) if they
want to use DAX?  ext4 will even support the unmodified ext2 fs, so it
shouldn't be a big hurdle, and it would avoid a lot of churn in ext2.
