Subject: xen-blkfront: Drop name and minor adjustments for emulated
scsi devices
From: Stefan Bader <[email protected]>
commit 196cfe2ae8fcdc03b3c7d627e7dfe8c0ce7229f9 upstream.
These were intended to avoid the namespace clash when representing
emulated IDE and SCSI devices. However that seems to confuse users
more than expected (a disk defined as sda becomes xvde).
So for now go back to the scheme which does no adjustments. This
will break when mixing IDE and SCSI names in the configuration of
guests but should be by now expected.
