Yes, but all of this is particularly retarded, there are exactly _2_
callers of this function. Keeping an out-of-line copy for one while
inlineing the other makes 0 sense.

Also, the amount of crap he needs to mark __always_inline doesn't make
much sense to me, is he building with -Os or something?
