The split lockdep patches are now in misc-next, I'd like to continue
with a piecemal steps with the whole rwsem series:
- preparatory stuff, like the annotations patches 1-10
- switch locks to rwsem (1 patch)
- post cleanups once things prove to be ok
So I'll take 1-10 now, this should not significantly affect things. We
have the data tickets in and I'd rather wait a bit before adding another
similarly intrusive change so we'd be able to identify where bugs
originate.
