Thanks a lot, I really appreciate that. The story here is that kib really wanted to commit another patch aiming for the vnode lock upgrade with a modify to lockmgr that I wasn't happy with (or more specifically that I really wished could be carried on in a different way). As this is a time-critical fix for him, that is probabilly a better compromise. I'll try to find some time and go with the full patchset I have in mind, changing this to using upgrade.
