    Description

      We had an MDS crash with the following assertion:

      ldlm_lock.c:770:ldlm_lock_addref()) ASSERTION( lock != ((void *)0) )

      The previous few minutes contained many lock timeouts and some node reconnections.

      The backtrace for the mdt_02_049 that hit the assertion was:

      ldlm_lock_addref
      mdt_reint_open
      mdt_reconstruct_open
      mdt_reconstruct
      mdt_reint_internal
      mdt_intent_reint
      mdt_intent_policy
      ldlm_lock_enqueue
      ldlm_handle_enqueue0
      mdt_enqueue
      mdt_handle_common
      mds_regular_handle
      ptlrpc_server_handle_request
      ptlrpc_main
      

      We were running lustre version 2.4.2-14chaos (see github.com/chaos/lustre).

      We cannot provide logs or crash dumps from this system.

            [LU-5632] ldlm_lock_addref()) ASSERTION( lock != ((void *)0) )

            Should be fixed for 2.4 with Oleg's patch from LU-5525.

            This is caused by the flaw patch of LU-4584, Oleg's correct fix from LU-5525 ( http://review.whamcloud.com/#/c/9488/) should fix the problem.
