      Description

      When I ran replay-dual test_26 with patch LU-7716 applied, I can see the complaint as:

      LustreError: 24453:0:(layout.c:2025:__req_capsule_get()) @@@ Wrong buffer for field `object_update_reply' (1 of 1) in format `OUT_UPDATE': 0 vs. 4096 (server)
      

      at test cleanup time.

      Then I made a patch to catch the debug log and backtrace. This is what I have got.

      Pid: 24453, comm: osp_up0-1
