[Qemu-devel] [PATCH v2 0/3] nbd: Adapt for dataplane

[Max Reitz]

For the NBD server to work with dataplane, it needs to correctly access
the exported BDS. It makes the most sense to run both in the same
AioContext, therefore this series implements methods for tracking a
BDS's AioContext and makes NBD make use of this for keeping the clients
connected to that BDS in the same AioContext.


v2:
 - Patch 1: Drop NBDClient::restart_write; checking whether
   NBDClient::send_coroutine is not NULL suffices [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

001/3:[0005] [FC] 'nbd: Drop nbd_can_read()'
002/3:[----] [--] 'block: Add AIO context notifiers'
003/3:[----] [--] 'nbd: Follow the BDS' AIO context'


Max Reitz (3):
  nbd: Drop nbd_can_read()
  block: Add AIO context notifiers
  nbd: Follow the BDS' AIO context
