We need update some metadata for some kinds of type block, such as dir3 leafn block records its blkno, we shall update it to the dead block blkno. Otherwise, before write the xfs_buf to disk, the verify_write() will fail in blk_hdr->blkno !=3D xfs_buf->b_bn, then xfs will be shutdown. We will get this warning: XFS (dm-0): Metadata corruption detected at xfs_dir3_leaf_verify+0xa8/0xe= 0 [xfs], xfs_dir3_leafn block 0x178 XFS (dm-0): Unmount and run xfs_repair XFS (dm-0): First 128 bytes of corrupted metadata buffer: 00000000e80f1917: 00 80 00 0b 00 80 00 07 3d ff 00 00 00 00 00 00 ......= ..=3D....... 000000009604c005: 00 00 00 00 00 00 01 a0 00 00 00 00 00 00 00 00 ......= .......... 000000006b6fb2bf: e4 44 e3 97 b5 64 44 41 8b 84 60 0e 50 43 d9 bf .D...d= DA..`.PC.. 00000000678978a2: 00 00 00 00 00 00 00 83 01 73 00 93 00 00 00 00 ......= ...s...... 00000000b28b247c: 99 29 1d 38 00 00 00 00 99 29 1d 40 00 00 00 00 .).8..= ...).@.... 000000002b2a662c: 99 29 1d 48 00 00 00 00 99 49 11 00 00 00 00 00 .).H..= ...I...... 00000000ea2ffbb8: 99 49 11 08 00 00 45 25 99 49 11 10 00 00 48 fe .I....= E%.I....H. 0000000069e86440: 99 49 11 18 00 00 4c 6b 99 49 11 20 00 00 4d 97 .I....= Lk.I. ..M.
