No shit. Locking, refcounting, serial drivers, yada, yada. Currently it's the worst widely-used subsystem in the tree - both 2.4 and 2.5 (and 2.2 is not much better). I've got some cleanups, but that will have to go slowly and carefully - otherwise we'll destroy the last remnants of 2.0 race prevention logics in there and that's the only thing that makes the current code kinda-sorta work most of the time.

BTW, somebody will have to document the tty driver and ldisc API. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
