<p>Hm, loop1 is the <tt style="background: #ebebeb; font-size: 13px;">lowerdir</tt> of the overlay - how are loop0 and sr0 involved, are these the backing files?</p>
<p>Though, the relevant part is <tt style="background: #ebebeb; font-size: 13px;">mntent.mnt.type == "overlay"</tt> and <tt style="background: #ebebeb; font-size: 13px;">mntent.mnt_dir == "/"</tt>. Matching for "overlay" is probably sufficient.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R241 KIO</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D15739">https://phabricator.kde.org/D15739</a></div></div><br /><div><strong>To: </strong>meven, Dolphin, VDG, tcanabrava, ngraham, elvisangelaccio<br /><strong>Cc: </strong>andriusr, fvogt, meven, elvisangelaccio, Codezela, davidc, tcanabrava, ndavis, romangg, bruns, davidedmundson, abetts, svenmauch, broulik, acrouthamel, kde-frameworks-devel, LeGast00n, michaelh, ngraham<br /></div>
