The basic problem is that heavy use of dsched (the disk scheduler) has caused crashes and lockups ever since dsched went into the tree, and is still causing crashes and lockups today. Several people have tried to bandaid it but honestly I think the only correct solution is to remove it and then start over from scratch at some future date with a better design.
So I would like to remove it, and I am soliciting opinions on that. -Matt Matthew Dillon <dil...@backplane.com>
