2005-07-01[PATCH] PCI: handle subtractive decode pci-pci bridge betterIvan Kokshaysky
With the number of PCI bus resources increased to 8, we can handle the subtractive decode PCI-PCI bridge like a normal bridge, taking into account standard PCI-PCI bridge windows (resources 0-2). This helps to avoid problems with peer-to-peer DMA behind such bridges, poor performance for MMIO ranges outside bridge windows and prefetchable vs. non-prefetchable memory issues. To reflect the fact that such bridges do forward all addresses to the secondary bus (transparency), remaining bus resources 3-7 are linked to resources 0-4 of the primary bus. These resources will be used as fallback by resource management code if allocation from standard bridge windows fails for some reason.

2005-06-29[PATCH] driver core: Add the ability to bind drivers to devices from userspaceGreg Kroah-Hartman
This adds a single file, "bind", to the sysfs directory of every driver registered with the driver core. To bind a device to a driver, write the bus id of the device you wish to bind to that specific driver to the "bind" file (remember to not add a trailing \n). If that bus id matches a device on that bus, and it does not currently have a driver bound to it, the probe sequence will be initiated with that driver and device. Note, this requires that the driver itself be willing and able to accept that device (usually through a device id type table). This patch does not make it possible to override the driver's id table.

2005-06-28[PATCH] blk: light iocontext opsNick Piggin
get_io_context needlessly turned off interrupts and checked for racing io context creations. Both of which aren't needed, because the io context can only be created while in process context of the current process. Also, split the function in 2. A light version, current_io_context does not elevate the reference count specifically, but can be used when in process context, because the process holds a reference itself.

2005-06-28[PATCH] blk: __make_request efficiencyNick Piggin
In the case where the request is not able to be merged by the elevator, don't retake the lock and retry the merge mechanism after allocating a new request. Instead assume that the chance of a merge remains slim, and now that we've done most of the work allocating a request we may as well just go with it. Also be rid of the GFP_ATOMIC allocation: we've got working mempools for the block layer now, so let's save atomic memory for things like networking. Lastly, in get_request_wait, do an initial get_request call before going into the waitqueue. This is reported to help efficiency.

2005-06-28[NET]: Remove gratuitous use of skb->tail in network drivers.David S. Miller
Many drivers use skb->tail unnecessarily. In these situations, the code roughly looks like: dev = dev_alloc_skb(...); [optional] skb_reserve(skb, ...); ... skb->tail ... But even if the skb_reserve() happens, skb->data equals skb->tail. So it doesn't make any sense to use anything other than skb->data in these cases. Another case was the s2io.c driver directly mucking with the skb->data and skb->tail pointers. It really just wanted to do an skb_reserve(), so that's what the code was changed to do instead. Another reason I'm making this change as it allows some SKB cleanups I have planned simpler to merge. In those cleanups, skb->head, skb->tail, and skb->end pointers are removed, and replaced with skb->head_room and skb->tail_room integers. Signed-off-by: David S.

2005-06-28[PATCH] ll_rw_blk: prevent huge request allocationsJens Axboe
Currently we cap request allocations at q->nr_requests, but we allow a batching io context to allocate up to 32 more (default setting). This can flood the queue with request allocations, with only a few batching processes. The real fix would be to limit the number of batchers, but as that isn't currently tracked, I suggest we just cap the maximum number of allocated requests to eg 50% over the limit. This was observed in real life, users typically see this as vmstat bo numbers going off the wall with seconds of no queueing afterwards. Behaviour this bursty is not beneficial.
