Message-ID: <m3r84wn4qj.fsf@lugabout.jhcloos.org> (raw)
In-Reply-To: <20030711140219.GB16433@suse.de>

First it has:

|>IO subsystem.
|>~~~~~~~~~~~~~
|>- Several different IO elevators are available to match different types
|>  of workload.  You can select which one to use with elvtune.
                                                       ^^^^^^^
and then:

|>Deprecated.
|>~~~~~~~~~~~
|>- elvtune is deprecated (as are the ioctl's it used).
    ^^^^^^^^^^^^^^^^^^^^^
|>  Instead, the io scheduler tunables are exported in sysfs (see below)
|>  in the /sys/block/<device>/iosched directory.
|>  Jens wrote a document explaining the tunables of the new scheduler at
|>  http://www.lib.uaa.alaska.edu/linux-kernel/archive/2002-Week-44/att-deadline-iosched.txt

Also, it is /sys/block/<device>/queue/iosched/ on my box.
