[PATCH] and more extras/multipath updates
* configure the multipath target with round-robin path selector and
conservative default for a start : yes it makes this release the first
really useful one.
* temporarily disable map creation for single path device due to current
restrictive defaults in the kernel target. Sistina should work it out.
* correct the strncmp logic in blacklist function.
Tested on StorageWorks with 2.6.0-test10-udm1 :
