It has, on sparc32 the hashed spinlock scheme is being used so it's a full 32-bit counter now.
Well, it's not even 32-bits, it's actually 31-bits since the value is declared as signed.
Only 64-bit platforms provide the atomic64_t implementation. We'd need to deal with that before making your suggested change. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
