Yup - adding to tree.

Suspend the device below & issue I/O so the loop won't exit
until you abort the suspend.  That's the reason for that code.

Not a problem yet: no user of that should do anything that needs
reverting should suspension fail, as per the comment (not a FIXME):
       /* This does not get reverted if there's an error later. */

If new targets or enhancements need new hooks then of course
we can consider adding them when the need arises.
