Subject: [dm-devel] [Patch 2 of 2]: scsi-dh + dm-mpath: propagate SCSI device deletion to multipath

The problem:
When a SCSI device attached to a device handler is deleted, userland processes currently performing I/O on the device will I/O hang forever.

Attached is the multipath layer part of the patch.
