I want to make sure the new REQ_OP_VERIFY is compatible with the
dm side as it is a generic interface.

Any comments on the dm side ? It will help me to respin the series for
V1 of this proposal.

I can review, but have you tested your XFS scrub usecase ontop of
the various DM devices you modified?

Also, you seem to have missed Keith's suggestion of using io_uring to
expose this capability.  If you happen to go that route: making sure
DM has required io_uring capabilities would be needed (IIRC there
were/are some lingering patches from Ming Lei to facilitate more
efficient io_uring on DM.. I'll try to find, could be I'm wrong).
