Formally, this should be

static atomic_t dropped_count = ATOMIC_INIT(0);

but no atomic_t implementations need that, and I'm sure that if one
turns up wchih _does_ need it (say, it has a spinlock inside its
atomic_t) then the kernel would break all over the place.

So perhaps we should formally state that the all-zeroes pattern is an
acceptable way of initialising an atomic_t.

In which case these:

y:/usr/src/linux-2.6.28> grep -r "atomic_t.*=.*ATOMIC_INIT" . | wc -l

become cleanup fodder.
