H A Dblkfront.cdiff 085def3f0a66da5c5a538d9b02df9e2e8b9dd8d6 Wed Dec 14 20:28:19 CET 2016 Dimitry Andric <dim@FreeBSD.org> In xbd_connect(), use correct scanf conversion specifiers for the
feature_barrier and feature_flush variables. Otherwise, adjacent
variables on the stack, such as sector_size, may be overwritten, with
disastrous results.

Note that I did not see a good reason to revert the addition of zero
checks introduced in r310013. Better safe than sorry.
