| Description |

Looking at an MDT under zfs, found that plain llogs, containing UPDATE_REC type entries, have 3 links. An example is: oi.88/0x240019a58:0x6:0x0 Note that the oi.88, oi.10, and update_log_dir entries all refer to the same underlying object/file. Per Di, there should be fewer links. |

Because putting these update log files under a name directory will help us understanding what these files are when accessing them with ZPL, so we probably want to keep as it is. If you are ok with that, let's close this ticket, and focus on |
