[PATCH 0/7] commit: Expose on-error option in QMP

[Kevin Wolf]

All other block jobs already provide a QMP option to control the error
handling policy. It's time to add it to commit, too.

Peter, I guess libvirt wants to expose this?

Nir, as you would probably assume, this is motivated by the recent
finding that VDSM has to preallocate the theoretical maximum for commit
operations because QEMU doesn't provide a way to reliably resize the
base image dynamically. If you ever want to improve that code, this will
enable you to do so from the QEMU side.
