      Hi,

      Coverity has found a strange piece of code in check_and_start_recovery_timer() function:

      if (!(lsi->lsi_flags | LDD_F_IR_CAPABLE))
      service_time += 2 * (CONNECTION_SWITCH_MAX +
      CONNECTION_SWITCH_INC);

      According to the tool, 'lsi->lsi_flags | LDD_F_IR_CAPABLE' is useless because it is always true. So it seems the developer meant to use '&' instead of '|'.

      But if we change the code accordingly, then we hit a number of issues because of unprotected access to recovery timer, as seen in https://maloo.whamcloud.com/test_sessions/96125f26-bc36-11e2-b013-52540035b04c
