title: Defining PATH_MAX for a filesystem?
body: <p>I'm presently writing a filesystem. The <a href="http://linuxmanpages.com/man2/statvfs.2.php" rel="noreferrer"><code>statvfs</code></a> (and even the <code>statfs</code>) structs contain a field specifying the maximum length of a name in that path. As <code>PATH_MAX</code> is defined in the <a href="http://www.manpagez.com/man/2/pathconf/" rel="noreferrer"><code>pathconf</code></a> manpage (<a href="http://www.manpagez.com/man/1/getconf/" rel="noreferrer"><code>getconf</code></a>), this means it is defined on a per-directory basis (and thus, determined by the underlying filesystem). How does one specify this value?</p>
