Ah yes, you mean, I take it, that the page fault handler would look at the user's program and emulate the faulting store instruction and return to the instruction after it. Very clever. And as long as we're going down that path, we should also consider changing exec() so instead of branching into the program, it just interprets it! - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
