[Qemu-block] [PATCH 0/2] block-stream: include base into job node list

[Andrey Shinkevich]

The block-stream job needs to own the base node as the limiter for
the copy-on-read operation. So, the base node is included in the
job node list by calling to the function block_job_add_bdrv().
Also, the block-stream job would not allow the base node to go
away due to the graph modification, e.g. when a filter node is
inserted between the bottom node and the base node.
For that reason, the flag BLK_PERM_GRAPH_MOD is unset in the
shared permission bit mask of the base node.
