this is very risky code; if addr is a 32 bit entity, then this is undefined behavior (which due to the vagities of x86 asm might get optimized out entirely). It is a lot safer to do (addr>>16)>>16 gcc will optimize that just fine, the difference is that it's still defined C behavior regardless of the type of addr. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
