I'm thinking that dm-crypt should probably set max_write_same_sectors to
0. It doesn't really make much sense for a crypto driver to pass that
command through.
Mike, do you want to look into this?
to audit DM relative to WRITE SAME too (will do once I understand what
added safety/constraints are needed).
But do we know mount to somwhow be issuing WRITE SAME requests? Martin,
why is it you weren't able to reproduce (I haven't attempted yet)?
