[Qemu-devel] [PATCH 00/14] block: Make blockdev-create a job and stable API

[Kevin Wolf <kwolf@redhat.com>]

This changes the x-blockdev-create QMP command so that it doesn't block
the monitor and the main loop any more, but starts a background job that
performs the image creation.

The basic job as implemented here is all that is necessary to make image
creation asynchronous and to provide a QMP interface that can be marked
stable, but it still lacks a few features that jobs usually provide: The
job will ignore pause commands and it doesn't publish progress yet (so
both current-progress and total-progress stay at 0). These features can
be added later without breaking compatibility.

At the end of the series, the interface is declared stable and the x-
prefix is removed.
