This patchset adds support for online resizing of block devices.
The first patch adds a new resize monitor command which call into
the existing image resize code. This is the meat of the series
and probably needs quite a bit of review and help as I'm not sure
about how to implement the error handling for monitor commands
correctly. Am I really supposed to add a new QERR_ definition
for each possible error? And if yes how am I supposed to define
them? The macros for them aren't exactly self-explaining.
The second patch adds a way to tell drivers about a resize, and the
third one adds a guest notification for config changes to virtio-blk
which allows the guest to pick it up without a rescan. I've just sent
the corresponding Linux guest driver patch to Rusty.
Changes from version 2 to version 3:
- add missing braces
- use device as the argument name for the device string
- also rename the HMP version of the command to block_resize
Changes from version 1 to version 2:
- also add a QMP command (block_resize)
- use the o format for the size in the monitor command
- fix typos
- use QERR_UNDEFINED_ERROR for errors instead of unstructured strings
- remove the CDROM hint check
- add a reason argument to the change callback
