Indeed, I missed that.  Checking the rest of the function, I see no problem here.

Based on that, I've just read msdosfs_readdir(), and the problem could be there:
"""
if (dep->de_FileSize - (offset - bias) <= 0)
"""
because dep->de_FileSize is an *unsigned* long, and the test only passes with 'offset - bias' exactly equal to 'de_FileSize'.  The assignment to `diff` in the loop above would be wrong as well.
