3.2.67-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Jan Kara <jack@xxxxxxx>
commit fef2e9f3301934773e4f1b3cc5c7bffb119346b8 upstream.
Currently, we ignore symlink component of type 2. But mkisofs and other OS'
seem to treat it as / so do the same for compatibility.
