xfs: strengthen btree pointer checks before use Instead of ASSERTing on null btree pointers in xfs_btree_ptr_to_daddr, use the new block number verifiers to ensure that the btree pointer doesn't point to any sensitive areas (AG headers, past-EOFS) and return -EFSCORRUPTED if this is the case. Remove the ASSERT because on-disk corruptions shouldn't trigger ASSERTs. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Dave Chinner <dchinner@redhat.com>
