[Qemu-devel] [PATCH 0/4] block: BdrvChildRole.drained_begin/end fixes

[Kevin Wolf]

While working on the series that converts block jobs to using a separate
BlockBackend, I noticed that I need to do some drain fixes first. So here they
are.

Patches 1 and 2 are just preparation, patches 3 and 4 are the actual fixes.

Kevin Wolf (4):
  block: Introduce bdrv_replace_child()
  block: Make bdrv_drain() use bdrv_drained_begin/end()
  block: Fix reconfiguring graph with drained nodes
  block: Propagate .drained_begin/end callbacks
