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.
