Quite possibly the 4.0 code has been removed ... if the 4.1 or 4.2 code will connect to a 4.0 server then the old code isn't needed. XFS and ext are similar - there's only one instance of xfs code which supports all versions, and I believe all the ext2 code is gone from the kernel - ext4 with journal switched off will quite happily read/write ext2.
