Hello Arjan and list, The documentation related to atomic operations says that the following functions should be called in SMP safe maner void atomic_add(int i, atomic_t *v); void atomic_sub(int i, atomic_t *v); void atomic_inc(atomic_t *v); void atomic_dec(atomic_t *v); since the implementation of these functions are prefixed with LOCK prefix (On i386 arch.) which either asserts LOCK# signal or performs cache locking which gauarentees coherency. Then why these functions should be called in SMP safe manner? - 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/ | ||||||||||||
