I've changed these two lines into:
if (sfs_mnt->procuid && len)
sfs_mnt->options[len] = '\0';
which I think was intended. That is, it strips the procuid
stuff from the options after adding in add_procuid

I just wonder why nobody cared to solve this. SUSE has this
in their kernel, perhaps they have solved it by themselves.
