FWIW, I would add the following to what you've already mentioned:

better off as
fsparam_flag_no("user_xattr", Opt_user_xattr),
fsparam_flag_no("acl", Opt_acl),

BTW, what's the point of using invalf() in contexts where
the return value is ignored? Why not simply go for errorf()
(or errorfc(), for that matter)?

I do plan that branch (or an equivalent, as far as filesystems
are concerned - there might be a bit of additional rework in
the beginning + currently missing modifications of docs) for
5.6. So updated patch would be welcome - I can do that myself,
but if you can rebase it on top of that branch it would save
