This patch brings the IP ECN handling up-to-date with repsect to RFC 3168. Mostly this means treating ECT(1) in the same way as ECT(0). Signed-off-by:

New version of the NETIF_F_LLTX for network devices patch. This allows network drivers to set the NETIF_F_LLTX flag and then do their own locking in start_queue_xmit. This lowers locking overhead in this critical path. The drivers can use try lock if they want and return -1 when the lock wasn't grabbed. In this case the packet will be requeued. For better compatibility this is only done for drivers with LLTX set, others don't give a special meaning to -1. Most of the modern drivers who have a lock around hard_start_xmit can just set this flag. It may be a good idea to convert the spin lock there to a try lock. The only thing that should be audited is that they do enough locking in the set_multicast_list function too, and not also rely on xmit_lock here. Now doesn't move any code around and does things with gotos instead. The loop printk is also still there even for NETIF_F_LLTX For drivers that don't set the new flag nothing changes.

Here's the optimization: if we know the remaining data exceeds the mtu, we do not need to fill up full of it. skb_prev: mtu +----------+--+-+ | | | | +----------+--+-+ ^ ^ skb_prev->len | maxfraglen appending data: +--------+ | | +--------+ ---------> length In this case, we know we need more fragment(s). So, let's fill up to maxfraglen (instead of mtu) to avoid needless copy in the next loop. Signed-off-by:Hideaki YOSHIFUJI <yoshfuji@linux-ipv6.org> Signed-off-by:

Avoid forcing use of the no-op scheduler for UBD; this may uncover some bugs in the UBD driver, and in fact uml-ubd-no-empty-queue.patch is needed to make this sure. But as of now, no other bugs have been discovered, so this should be safe. Signed-off-by:

Avoid using, in the UBD driver, the elv_queue_empty function. It's for the block layer only; in fact, the Anticipatory Scheduler can return NULL with elv_next_request() even if the queue is not empty, because it waits for the process to send another request before seeking on the disk. In fact, if (with uml-ubd-any-elevator) we let UBD use any scheduler, elevator=as will make the UBD driver Oops, if we don't have this patch. Signed-off-by:

I noticed a large machine was doing about 400,000 context switches per second when oprofile was enabled. Upon closer inspection it looks like we were rearming the buffer sync timer without modifying the expire time. Now that we have schedule_delayed_work_on I believe we can remove the timer completely. Each cpu should be offset by 1 jiffy so they dont all fire at the same time. I bumped DEFAULT_TIMER_EXPIRE from 2 to 10 times a second to be sure we reap cpu buffers. With the following patch the same large machine gets about 4000 context switches per second. Signed-off-by:

The problem here is, finished_one_bio() shouldn't call aio_complete() since no work has been done. I have a fix for this - can you verify this ? I am not really comfortable with this "tweaking". (I am not really sure about IO errors like EIO etc. - if they can lead to calling aio_complete() twice) Fix is to call aio_complete() ONLY if there is something to report. Note the we don't update dio->result with any error codes from get_user_pages(), they just passed as "ret" value from do_direct_IO(). Signed-off-by:
