You meant to say atomic_dec_and_lock() ? Dunno if we ever get there, but
typically dec_and_lock is fairly refcounty, but I suppose it is possible
to have !refcount users, in which case we're eternally stuck with it.

But a quick look at the sites you converted, they all appear to be true
refcounts, and would thus benefit from being converted to refcount_t.
