Hi,
We have a POWER machine with a broken multipath setup. Analysis shows
that the RDAC driver is being used even though it shouldn't.
The vendor/product is:
IBM,IPR-0 65C61818
There is an entry for this device:
/* IBM IPR */
.vendor = "IBM",
.product = "IPR.*",
Unfortunately it looks like a previous entry is matching against this
(since we do a regex match):
/* IBM DS5000 */
.vendor = "IBM",
.product = "1818",
There are a number of IBM entries that have this issue. The following
patch ensures we match against the entire product ID.
Anton
