[Qemu-devel] [RFC PATCH 00/16] qcow2: Basic version 3 support

[Kevin Wolf <kwolf@redhat.com>]

While this is not quite ready to be merged, I think the important stuff is done
and works (it survives qemu-iotests at least) and probably now is the right
time to start getting feedback. I'm going to get this merged before the 1.1
soft freeze.

What's left is probably some cleanup, adding more new test cases and obviously
fixing whatever bugs come up.

Kevin Wolf (15):
