Subject: RE: [PATCH 1/4] exfat: Simplify exfat_utf8_d_hash() for code points
 above U+FFFF

> So partial_name_hash() like I used it in this patch series is enough?

I think partial_name_hash() is enough for 8/16/21bit characters.

Another point about the discrimination of 21bit characters:
I think that checking in exfat_toupper () can be more simplified.

 ex: return a < PLANE_SIZE && sbi->vol_utbl[a] ? sbi->vol_utbl[a] : a;
