Christoph, don't take your frustrations out on me. I've several times in this thread said that I'd LIKE to have > PAGE_SIZE support in the page cache. I WROTE the initial pktcdvd driver that is a primary example of these hacks, I'm very well aware of the pain and bugs involved with that. But don't push large pages as the only solution to larger ios, because that is trivially not true. -- Jens Axboe - 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/
