[dm-devel] Requiring a hwtable entry for a dm target device?



Currently a dm target device which is not blacklisted need not have a
corresponding hwentry in either libmultipath/hwtable.c or
/etc/multipath.conf
for the target device to be recognized and a multipath mapped device
created for it.  Is this desirable, possibly for multipathing to JBOD?

An alternative is to require that a hwentry be found and fail to recognize
the target device otherwise.  Doing so has the distinct advantage of being
able to use the regular expression matching logic in find_hwe() to
effectively
blacklist a target device based on the contents of the target device's
vendor
and product device attributes.
