I've committed most of the 'lets pull the USB cord and see what happens'
work.
I've also committed a ton of HAMMER work that allows it to handle
catastrophic I/O errors (aka the same pulling of the USB cord) and
still be able to umount and remount the sucker.
CAM still has a few memory leaks, and there could be additional bugs
that can cause panics. I am going to continue messing with it and
try to track down the memory leaks, and any additional panics I come
across.
I used the same HAMMER filesystem on my external drive through all the
testing, which involved starting up a big cpdup to the filesystem and
then pulling the USB plug in the middle of it. I pulled the plug at
least 50 times while debugging the panics and crashes and didn't lose
the filesystem. I think that's pretty cool :-)
