[Qemu-devel] [PATCH for-2.3 0/4] blockdev: support dataplane in remaining QMP commands

[Stefan Hajnoczi]

This patch series adds virtio-blk dataplane support for the following QMP
commands:

 * eject
 * change
 * change-backing-file
 * block_passwd
 * blockdev-snapshot-delete-internal-sync

This requires acquiring and releasing the BlockDriverState's AioContext so that
the IOThread does not run while the monitor command is executing.

Monitor commands that use AioContext can be unblocked in the virtio-blk
dataplane op blockers list.

After this series only the transaction QMP command remains to be converted.

Stefan Hajnoczi (4):
  blockdev: acquire AioContext in blockdev-snapshot-delete-internal-sync
  blockdev: check for BLOCK_OP_TYPE_INTERNAL_SNAPSHOT_DELETE
  blockdev: acquire AioContext in eject, change, and block_passwd
  blockdev: acquire AioContext in change-backing-file
