Hi all, I am encountering alot macros in the code. I did not understand what those macro means. Can anyone explain them and the use of them putting them like that. "unlikely" "always_inline" -- defined at the signature of the function. "inline" -- I know inline keyword in compiler is used to place the code in to the caller function at the time of compiler, but why declared as macro Any help would be appreciated. -- Regards, Sri. -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
