Against test5-mm4. This is commented a bit better than the previous version I sent to Al and Jens.
sysfs interface is /sys/block/*/queue/io_scheduler. Valid values are as, deadline, noop, cfq. Switching schedulers under disk load works fine in my tests. sysfs stuff seems to be working nicely and handles lingering userspace references properly.
Review of the kobject / sysfs stuff would be especially helpful. Thanks.
