[v6,00/11] Exposing backing-chain allocation over NBD

Message

Eric Blake Oct. 27, 2020, 5:05 a.m. UTC

v5 was here:
https://lists.gnu.org/archive/html/qemu-devel/2020-10/msg07124.html

Also available at:
https://repo.or.cz/qemu/ericb.git/shortlog/refs/tags/nbd-alloc-depth-v6

Since v5:
- rebase to master (mostly affects 8/11) [Vladimir]
- drop v5 1/12, and replace with new v6 1/11 [Markus]
- rearrange series to complete 'bitmaps' before 'allocation-depth'
- don't alter 'nbd-server-add' [Peter]
- simplify qemu:allocation-depth to just be an integer [Vladimir]

I want at least 1-7/11 in a pull request this week for 5.2 soft
freeze, but it would also be nice to get the feature of 8-10/11 in as
well.  11/11 is less important, but a nice followup to 2/11.

(Oh, and my KVM Forum presentation this Friday uses these patches ;)

Eric Blake (11):
  block: Simplify QAPI_LIST_ADD
  qapi: Make QAPI_LIST_ADD() public
  nbd: Utilize QAPI_CLONE for type conversion
  nbd: Update qapi to support exporting multiple bitmaps
  nbd: Simplify qemu bitmap context name
  nbd: Refactor counting of metadata contexts
  nbd: Allow export of multiple bitmaps for one device
  block: Return depth level during bdrv_is_allocated_above
  nbd: Add new qemu:allocation-depth metadata context
  nbd: Add 'qemu-nbd -A' to expose allocation depth
  qapi: Use QAPI_LIST_ADD() where possible
