There are two ways to scrub an inode -- calling xfs_iget and checking the raw inode core, or by loading the inode cluster buffer and checking the on-disk contents directly. The second method is only useful if _iget fails the verifiers; when this is the case, sc->ip is NULL and calling the tracepoint will cause a system crash. Therefore, pass the raw inode number directly into the _preen and _warning functions. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Darrick J.
