I think that makes a lot of sense, and to be honest other MSG_ flags make useful sense and have meaningful semantics that might be helpful elsewhere if ever coded that way. If you want to do this the first job is going to be to sort out the way non-block is propogated to device driver read/write handlers. At the moment they all check filp->f_flags Alan - 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/
