[Qemu-devel] [PATCH v2 for-2.9] block: Declare blockdev-add and blockdev-del supported

[Markus Armbruster]

It's been a long journey, but here we are.

The supported blockdev-add is not compatible to its experimental
predecessors; bump all Since: tags to 2.9.

x-blockdev-remove-medium, x-blockdev-insert-medium and
x-blockdev-change need a bit more work, so leave them alone for now.

Signed-off-by: Markus Armbruster <address@hidden>

v2:
* Another "command is considered experimental" comment dropped [Max]
* More Since: tags updated to 2.9, commit message improved, R-bys dropped
