[Qemu-devel] [PATCH 0/3] allow online resizing of block devices

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.
