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[PATCH] ITIMER_REAL: fix possible deadlock and raceOleg Nesterov
As Steven Rostedt pointed out, there are 2 problems with ITIMER_REAL timers. 1. do_setitimer() does not call del_timer_sync() in case when the timer is not pending (it_real_value() returns 0). This is wrong, the timer may still be running, and it can rearm itself. 2. It calls del_timer_sync() with tsk->sighand->siglock held. This is deadlockable, because timer's handler needs this lock too.

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.

2005-06-27[PATCH] PCI: DMA bursting adviceDavid S. Miller
After seeing, at best, "guesses" as to the following kind of information in several drivers, I decided that we really need a way for platforms to specifically give advice in this area for what works best with their PCI controller implementation. Basically, this new interface gives DMA bursting advice on PCI. There are three forms of the advice: 1) Burst as much as possible, it is not necessary to end bursts on some particular boundary for best performance. 2) Burst on some byte count multiple. A DMA burst to some multiple of number of bytes may be done, but it is important to end the burst on an exact multiple for best performance. The best example of this I am aware of are the PPC64 PCI controllers, where if you end a burst mid-cacheline then chip has to refetch the data and the IOMMU translations which hurts performance a lot. 3) Burst on a single byte count multiple. Bursts shall end exactly on the next multiple boundary for best performance. Sparc64 and Alpha's PCI controllers operate this way. They disconnect any device which tries to burst across a cacheline boundary. Actually, newer sparc64 PCI controllers do not have this behavior. That is why the "pdev" is passed into the interface, so I can add code later to check which PCI controller the system is using and give advice accordingly. Signed-off-by: David S.

This is an updated version of Ben's fix-pci-mmap-on-ppc-and-ppc64.patch which is in 2.6.12-rc4-mm1. It fixes the patch to work on PPC iSeries, removes some debug printks at Ben's request, and incorporates your fix-pci-mmap-on-ppc-and-ppc64-fix.patch also. Originally from Benjamin Herrenschmidt <benh@kernel.crashing.org> This patch was discussed at length on linux-pci and so far, the last iteration of it didn't raise any comment. It's effect is a nop on architecture that don't define the new pci_resource_to_user() callback anyway. It allows architecture like ppc who put weird things inside of PCI resource structures to convert to some different value for user visible ones. It also fixes mmap'ing of IO space on those archs.

2005-06-27[PATCH] acpi hotplug: decouple slot power state changes from physical hotplugRajesh Shah
Current acpiphp code does not distinguish between the physical presence and power state of a device/slot. That is, if a device has to be disabled, it also tries to physically ejects the device. This patch decouples power state from physical presence. You can now echo to the corresponding sysfs power control file to repeatedly enable and disable a device without having to physically re-insert it.
