Subject: [PATCH] xfs_db: refactor multi-fsb object detection decision making
Pull the "is this a multi-fsb object" decision into a separate function
that we can keep close to the actual multi-fsb object dispatcher. We
will soon make the machinery more complex so we do this to avoid having
a big hairy if statement.
