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

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blockdev: update outdated qmp_transaction() comments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
