[Qemu-devel] [PATCH v2 0/6] nbd: Use BlockBackend

[Max Reitz <mreitz@redhat.com>]

>From the block layer's perspective, the nbd server is pretty similar to
a guest device. Therefore, it should use BlockBackend to access block
devices, just like any other guest device does.

This series consequently makes the nbd server use BlockBackend for
referencing block devices.


v2:
- Added patch 6, which converts qemu-nbd to BlockBackend as far as
  reasonable [Paolo]


git-backport-diff against v1:

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

001/6:[----] [--] 'block: Lift more functions into BlockBackend'
002/6:[----] [--] 'block: Add AioContextNotifier functions to BB'
003/6:[----] [--] 'block: Add blk_add_close_notifier() for BB'
004/6:[----] [--] 'nbd: Change external interface to BlockBackend'
005/6:[----] [--] 'nbd: Use BlockBackend internally'
006/6:[down] 'qemu-nbd: Use BlockBackend where reasonable'
