    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
      update_log_dir/[0x240019a58:0x6:0x0]
      oi.10/0x20000000a:0x9:0x0/[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.
