[Qemu-devel] [PATCH v3 00/13] More block-related fixes and cleanups

[Markus Armbruster]

I'm working on cleanly separating block device host and guest parts.
I'd like to route all this work through Kevin's block tree.  This is
still just preliminaries.

There will be at least one more round of cleanup & fixes before
blockdev_add proper.  I intend to start with a minimal QMP-only
version, then add features.

v3: cover close of snapshot device, not just delete
    clean up bdrv_snapshots()

v2: plug leaks pointed out by Kevin Wolf
    fix qdev_prop_set_drive() to set the property only when attach
    succeeded (free_drive() will die without this)

Markus Armbruster (13):
  scsi: scsi_bus_legacy_handle_cmdline() can fail, fix callers
  ide: Make it explicit that ide_create_drive() can't fail
  blockdev: Remove drive_get_serial()
  blockdev: New drive_get_by_blockdev()
  blockdev: Clean up automatic drive deletion
  qdev: Decouple qdev_prop_drive from DriveInfo
  blockdev: drive_get_by_id() is no longer used, remove
  block: Catch attempt to attach multiple devices to a blockdev
  savevm: Survive hot-unplug of snapshot device
  block: Clean up bdrv_snapshots()
  block: Fix virtual media change for if=none
  ide: Make PIIX and ISA IDE init functions return the qdev
  pc: Fix CMOS info for drives defined with -device
