[Qemu-devel] [PATCH 0/8] Split ide-drive and scsi-disk qdevs, and more

[Markus Armbruster <armbru@redhat.com>]

This patch series is about purging the "type hint" from the block
layer.  My previous series cleaned up improper uses it.  Remaining
uses are info block and qdevs ide-drive, scsidisk.

Remove the type hint from info block.  Its value is unreliable anyway.

ide-drive and scsi-disk can either act as disk or as CD drive.  They
use their drive's type hint to decide between disk and CD.  This is
unclean.  Disk vs. CD needs to be in qdev, not BlockDriverState,
because it belongs to the drive's guest part.

Split them into separate devices for disk and CD.  Keep the old ones
for backward compatibility.

Bonus fix: reject empty drives unless media is removable (1-3/8).
