<h2>FAT (msdosfs) infrastructure work</h2>
<p><strong>Technical Contact</strong>: <a
href="mailto:rwatson@FreeBSD.org">&a.rwatson;</a></p>
<p>The FreeBSD FAT implementation, msdosfs, offers scope for a number of
projects:</p>
<ul>
<li>General cleanup.</li>
<li>Introduce appropriate locking to make the file system operate without
the Giant lock (MPSAFE).</li>
<li>Make msdosfs robust in the presence of unexpected disk removal, since
it is frequently used with removable devices.</li>
</ul>
<p>It is unclear to what extent the last of these items, arguably the most
useful, will require modifying surrounding infrastructure such as BIO,
GEOM, and VM.</p>
<p><strong>Requirements</strong>:</p>
<ul>
<li>Strong C programming skills.</li>
<li>Familiarity with concurrent programming techniques.</li>
<li>Familiarity with FAT file system layout.</li>
<li>Familiarity with virtual file system and virtual memory.</li>
</ul>
