Right, we could just skip the 8.3 name matching and go straight to the
longname match in fat_search_long(). I wonder if anyone ever relies on
the 8.3 matching when a file has a long name on Linux?

It would be only a few lines of code difference between the two
drivers - is it worth the maintainence overhead of splitting it up?

Maybe a mount option to ignore 8.3 names for files with long names
would be better? Perhaps even the default?
