Are there drivers which take longer to land code for than others? Like this? subtree: None (1724 patches): Average: 28.7 median: 11.0 subtree: nova/virt/ (476 patches): Average: 34.5 median: 18.0 subtree: nova/virt/hyperv/ (38 patches): Average: 46.8 median: 33.0 subtree: nova/virt/libvirt/ (224 patches): Average: 35.9 median: 18.0 subtree: nova/virt/xenapi/ (72 patches): Average: 39.5 median: 20.0 subtree: nova/virt/vmwareapi/ (134 patches): Average: 38.7 median: 26.0 >> When looking at these numbers two things stick out out: >> >> * We successfully use recheck an awful lot.

That's the distribution, percentage-wise, I'd expect to see for the 4 in-tree virt drivers.
