Subject: [PATCH] RH: Remove the property blacklist exception builtin
Multipath set the default property blacklist exceptions to
(ID_SCSI_VPD|ID_WWN). This has the effect of blacklisting some internal
devices. These devices may never have multiple paths, but it is nice
to be able to set multipath up on them all the same. This patch simply
removes the default, and makes it so that if no property
blacklist_exception is given, then devices aren't failed for not matching
it.
