But the central point still stands: if all you do is atomic_set() and atomic_read(), then using atomic_t doesn't buy you anything. Just look at what atomic_read() expands to -- using it isn't protecting you against anything, so either you have a race, or you were safe without atomic_t. The only point to atomic_t is so that you can safely do read-modify-write things like atomic_inc(). - R. - 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/ | ||||||||||||
