H A Dblock.hdiff 5a6684d2b957f9ec75d7ed7b14332293abec1d6c Wed Jun 25 14:40:09 CDT 2014 Jeff Cody <jcody@redhat.com> block: add helper function to determine if a BDS is in a chain

This is a small helper function, to determine if 'base' is in the
chain of BlockDriverState 'top'. It returns true if it is in the chain,
and false otherwise.

If either argument is NULL, it will also return false.
