Popped into #kernelnewbies briefly on Friday and "met", IIRC, davej, willy and one or two others. Over the weekend I poked at the loopback block device lockups in 2.3.99 but didn't come to any earth-shattering conclusions. As part of that I ported the IKD patch to 2.3.99-pre3, but I've not done anything useful with it (read: sent it to Andrea) yet.
Some other interesting stuff may be happening, but I can't talk about that right now.
Advogato really should allow people to set the date on their diary entries..
