Here's my current error handling patchset, against Chris's current
for-linus branch.

As before, it's almost all in preparation for actual error handling.
After a chat with Chris last week about some of the bits I thought
might be contentious, I went ahead with the next step and converted
struct extent_state allocations to use a mempool in front of the slab
cache it was using already. This means that non-atomic callers can't
catch an -ENOMEM and that means that non-atomic version of
{set,clear,convert}_extent_bit can return void.  This changes the
previous patch set quite a bit since the {set,clear,convert}_extent_bit
error push-up patches are now entirely obsolete.

The run down:
- extent_state allocations -> mempool
- delayed_ref allocations -> mempool
- a ton of int -> void changes
- add btrfs_panic
- a few cleanups where I ran into them
