Just curious: is there a technical reason we couldn't spin an -rc5 today (with just the fix to this issue), and slip the schedule only by two days instead of a full week? And/or shorten the time for testing -rc5 from the usual 7 days into 5? I don't know what other constraints we have to play with, so feel free to tell me that my idea is not feasible. Also, while I'm a block layer contributor, I'm not one of its co-maintainers, so I'd trust the replies from others a bit more than mine when deciding what to do here. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
