I think I managed to include everyone's patches this time.
. Includes the latest rbtree-based IO scheduler from Jens. This version
appears to do all the right things and in brief testing has at least the
same IO performance as the linear-search insertion, and shows lower CPU
costs.
The large queues which this code enables have tickled a bug in the
writeback code. With more than 40% of physical memory in a single queue
something is going for a bit of a spin and is consuming too much CPU.
It's not a fatal problem but can affect benchmarking. It will only
exhibit on smallish machines (<512 megabytes of RAM) and will be less
likely to happen on IDE systems. IDE has smaller requests than
SCSI and the total memory which can be placed under writeback is much less.
. There's a patch here which teaches the request queues to unplug themselves
if there are four requests queued or if the queue has been idle for three
milliseconds. Instrumentation shows that around 5 to 10% of requests are
getting an earlier start than they would have without this patch, but there
doesn't seem to be much benefit from brief testing. It may help AIO, which
would otherwise have to unplug all the queues in the machine with every
request.
It did allow some rather awkward unplugging code in lots of other places
to be pulled out.
