From: Christoph Hellwig hch@lst.de
commit 6471e9c5e7a109a952be8e3e80b8d9e262af239d upstream.
We know the version is 3 if on a v5 file system. For earlier file systems formats we always upgrade the remaining v1 inodes to v2 and thus only use v2 inodes. Use the xfs_sb_version_has_large_dinode helper to check if we deal with small or large dinodes, and thus remove the need for the di_version field in struct icdinode.
