[Qemu-devel] [PATCH 0/4] blockdev: support dataplane in QMP 'transaction' command

[Stefan Hajnoczi <stefanha@redhat.com>]

These patches make the QMP 'transaction' command work with virtio-blk
dataplane.  Each 'transaction' action must take care to acquire AioContext
around BlockDriverState accesses.  Once that protection is in place we can
unblock the op blockers for these commands.

The meat is in Patch 3.

Patches 1 & 2 are minor cleanups.
Patch 4 protects the external snapshot command (oops, we forgot!).

Stefan Hajnoczi (4):
  blockdev: update outdated qmp_transaction() comments
  blockdev: drop unnecessary DriveBackupState field assignment
  blockdev: acquire AioContext in QMP 'transaction' actions
  blockdev: check for BLOCK_OP_TYPE_EXTERNAL_SNAPSHOT
