--- Comment #2 from Zorro Lang (zlang@redhat.com) ---
208 error = xfs_trans_get_buf(*trans, mp->m_ddev_targp,
209 child_blkno,
210 XFS_FSB_TO_BB(mp,
mp->m_attr_geo->fsbcount), 0,
211 &child_bp);
212 if (error)
213 return error;
--> 214 error = bp->b_error;
I think this place is wrong, why not use child_bp->b_error? The 'bp' has been
freed by:
160 xfs_trans_brelse(*trans, bp); /* no locks for later trans */
right?
