v2: add
If the wwid changed, the device is no longer the same, so sending add
events to the devices partitions doesn't make any sense.

If a device with a scsi name identifier has an unknown prefix,
parse_vpd_pg83() needs to advance to the next identifier, instead of
simply trying the same one again in an infinite loop.

This patchset has minor fixups that were either suggested by Martin, or
came up through the disussions about my "Handle remapped LUNs better"
patchset.
Benjamin Marzinski (4):
libmultipath: avoid infinite loop with bad vpd page 83 identifier
libmultipath: fix priorities in parse_vpd_pg83
Instead of looping through parents and checking, just call
udev_device_get_parent_with_subsystem_devtype() to get the
right one.

The priorities for the EUI-64 (0x02) and NAME (0x08) scsi identifiers in
parse_vpd_pg83() don't match their priorities in 55-scsi-sg3_id.rules.
Switch them so that they match.

Better to also convert blk-sysfs.c:queue_poll_show().
