As a matter of coding style, I prefer #define cmpxchg_local cmpxchg #define cmpxchg64_local cmpxchg64 Which makes it absolutely clear that they are the same code. With your patch, humans have to do a string compare of two defines to see if they are the same. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
