Agreed, and I thought we discussed that already on the ext4 list.

I don't see them as any worse than existing checks. For 32-bit systems we only ever had a 32-bit in-memory version anyway so using only the low 32 bits of i_version in f_version is no more racy than in the past. For 64-bit systems using the full on-disk i_version is possible.
