The function name is a little vague too I suppose (will the inode ever get larger than large? :P). I wonder if something like _has_v3_inode() is more clear, but we can always change it easily enough and either way is better than hascrc() IMO.

I'm not too fond of the v3 name as the check also guards any newer version (but then again I hope we never need to rev the version..)

Not sure about larger than large inodes though -- the last di_flags2 could be made to mean "...and now expand structure by X bytes" whenever we run out of space.
