From: "J. Bruce Fields" <[email protected]> inode_query_iversion() has side effects, and there's no point calling it when we're not even going to use it.
We check whether we're currently processing a v4 request by checking fh_maxsize, which is arguably a little hacky; we could add a flag to svc_fh instead. Signed-off-by: J.
