From: Christoph Hellwig <hch@xxxxxx>
commit b81b79f4eda2ea98ae5695c0b6eb384c8d90b74d upstream.
Add a new wrapper to check if a file system supports the v3 inode format
with a larger dinode core. Previously we used xfs_sb_version_hascrc for
that, which is technically correct but a little confusing to read.
Also move xfs_dinode_good_version next to xfs_sb_version_has_v3inode
so that we have one place that documents the superblock version to
inode version relationship.
