RE: [PATCH v2 2/9] ext2: tell DAX the size of allocation holes

From: Christoph Hellwig [mailto:hch@infradead.org]

The mail is basically unparsable (hint: you can use a sane mailer even with
exchange servers :)).

That rather depends on how the Exchange servers are configured ... this isn't the
appropriate place to discuss IT issues though.

Either way we need to get rid of buffer_heads, and another aop that is entirely
caller specific is unaceptable.  That being said your idea doesn't sounds
unreasonable, but will require a bit more work and has no real short-term
need.

So your proposal is to remove buffer_heads from ext2?
