[Qemu-devel] [PATCH] qapi-schema: Update description for NewImageMode

[Max Reitz]

If the NewImageMode is "absolute-paths" but no backing file is available
(e.g., when mirroring a device with an unbacked image), the target image
will not be backed either. This patch updates the documentation in
qapi-schema.json accordingly.

Trivial enough to include in 1.7, if desired.

  It seems 2nd line should start with space, how about:
# @absolute-paths: QEMU should create a new image with absolute paths,
#                  the new image would usually have a backing file. If
#                  no backing file available, the new image will not be
#                  backed either.
