The strength of Tridge's approach over alternatives may be that it is clearer
to only create one name (always) and that it is relatively small.
Its weakness in my opinion is that as a sideeffect it prevents saving mixed
case file names.

There are various ways to disable (only) creating long file names, ie
to remove the ability
to create files longer than 8.3 from this module. Tridge's approach (which
basically avoids saving the alternate name, the mixed case name) works.
I realize that there are other ways to do this with trivial #ifdefs in
namei_vfat.c (see
vfat_build_slots and vfat_create_shortname), and when I tried other approaches
they worked too, although you may prefer Tridge's approach.
