Agreed!  It's a very common feature request so it'll be great to get this
in the tree.  This information is sort of available in
/sys/block/<backend-dev>/stat but it's not terribly reliable in my
experience (it's always zero's for loop devices IIRC).

These patches are missing Signed-Off-By lines too btw.  When you resubmit,
make sure to include those.

Thanks,
