      btrfs: fix inconsonant inode information · 2f7e33d4
      Miao Xie 提交于
      When iputting the inode, We may leave the delayed nodes if they have some
      delayed items that have not been dealt with. So when the inode is read again,
      we must look up the relative delayed node, and use the information in it to
      initialize the inode. Or we will get inconsonant inode information, it may
      cause that the same directory index number is allocated again, and hit the
      following oops:
      
      [ 5447.554187] err add delayed dir index item(name: pglog_0.965_0) into the
      insertion tree of the delayed node(root id: 262, inode id: 258, errno: -17)

      Fix it by reusing the old delayed node.
