It all depends on how you use the file descriptor. If you see a file descriptor as an opaque handle (like it should be, really), that is simply passed to the OS to use services exposed by the handle, you will be fine independently from the values handed out by the OS. It was for the exactly this guarantee that created the problems, with ppl relying on it for indexing table, closing all files < NR_FILE and so on. - Davide - 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/
