<p>The vm uses a splay tree to lookup pages associated with an offset and a
file. This tree structure is space inefficient and cache inefficient for
large objects. This project will be to replace the splay with a dynamic
depth page-table like structure similar to a radix tree. This will improve
large object performance and reduce the size of the vm_page.</p>
<p><strong>Requirements</strong>:</p>
<ul>
<li>Strong knowledge of C.</li>
<li>Familiarity with concepts of virtual memory and advanced data
structures and algorithms.</li>
