No checking multiple variables, no #ifdefing, something very streamlined. By userspace I assume you mean post-processing, i.e., if the user/library/etc needs to log events they use the same simple facility. I think we agree to optimize/streamline performance for the gathering and do work in the post processing. There is an outstanding patch that makes strides in this direction. -bob Robert Wisniewski The K42 MP OS Project http://www.research.ibm.com/K42/ [EMAIL PROTECTED] - 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/
