vfs: vfs_dedupe_file_range() doesn't return EOPNOTSUPP It returns EINVAL when the operation is not supported by the filesystem. Fix it to return EOPNOTSUPP to be consistent with the man page and clone_file_range(). Clean up the inconsistent error return handling while I'm there. (I know, lipstick on a pig, but every little bit helps...) Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.
