From: Mike Rapoport rppt@linux.vnet.ibm.com

commit 36447456e1cca853188505f2a964dbbeacfc7a7a upstream.

The switch to uuid_t invereted the logic of verfication that &entry->fsuuid is zero during parsing of "fsuuid=" rule. Instead of making sure the &entry->fsuuid field is not attempted to be overwritten, we bail out for perfectly correct rule.
