Subject: xen: add block resize support for xen disks
|
||
|
|
|
||
|
|
Provide monitor naming of xen disks, and plumb guest driver
|
||
|
|
notification through xenstore of resizing instigated via the
|
||
|
|
monitor.
|
||
|
|

|
|
[BR: minor edits to pass qemu's checkpatch script]
|
||
|
|
[BR: significant rework needed due to upstream xen disk qdevification]
|
||
|
|
[BR: At this point, monitor_add_blk call is all we need to add!]
