I guess I should have called the parameter "ret" instead of "rc", but I didn't expect people to get confused. 'rc' is the value of the expression when the loop terminates. That's what makes the most sense, because the developer will want to know what that value is. If you're expression happens to rely on negative logic (e.g. wait until a bit is cleared), then of course it's going to appear "backwards" when you test it. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
