I see. OK, will it hurt if would do hpfs_truncate() prior to the call of
hpfs_file_write()?

I can toss the code for that in - preserving the current behaviour, but
allowing to get rid of locking. Would you mind such a variant? It's not
like the thing was going to take a lot of time - straightforward copy of
FAT version would go.
