[Qemu-devel] [PATCH v4 0/9] blockdev: (Nearly) free clean-up work

[Max Reitz <mreitz@redhat.com>]

After a lot has been restructed in the block layer in the past, we can
now reap at least one of the fruits: Make bdrv_open() return a BDS!


v4:
- Rebased
- Patch 4:
  - Fixed the comment above blk_new_open() (we are no longer calling
    blk_new_with_bs())
  - Dropped the blk_new_with_bs() declaration in sysemu/block-backend.h
- Patch 9: Added


git-backport-diff against v3:

Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
