<h2>Port the "Pluggable Disk Schedulers" SoC project to current/GEOM</h2>
<p><strong>URL</strong>: <a
href="http://wikitest.freebsd.org/moin.cgi/Hybrid">The Pluggable Disk
Schedulers SoC project</a></p>
<p>Our "Pluggable Disk Schedulers" SoC project resulted in code which
solved the problem where large sequential I/O requests, or certain
access patterns from one or a few processes, might almost completely
starve other processes. It is available as a patch for RELENG_4 and
RELENG_5. Unfortunately the code in FreeBSD-current (and RELENG_6)
changed too much, so that the patches can not be committed. The goal
of this project is to port the pluggable disk schedulers to the GEOM
framework.</p>
<p><strong>Requirements</strong>:</p>
<ul>
<li>Ability to read and understand foreign C code.</li>
<li>Ability to write C code.</li>
<li>Knowledge of GEOM (or interest in getting familiar with it).</li>
</ul>
