So I have to confess that I've lost track of where we stand with this.
Holidays and moving house will do that...apologies. In any case, I have a
couple of additional comments.
Hmm, most of this document is*not* an admin-guide at all. The only
sections that really belong in that category are "What is FUSE?" and
"Control filesystem" and maybe some of the definitions as well. The
mount options for fuse filesystem are not generally usable for
actually performing a mount, most of those are actually internal
details of the filesystem implementation.
So I suggest leaving this file under Documentation/filesystems/ for
now and later work towards splitting out the admin-guide parts into a
separate document.
