    Description

      Some parts of Lustre debugging have been superseded by newer kernel features (such as CFS_CHECK_STACK) and should be removed.

      Certain subsystems stack custom macros on-top of Lustre's already custom debugging. Those should be simplified if possible.

      Other subsystems use low-level debugging functions such as libcfs_debug_msg. These should use the higher level macros. That way, the underlying debugging implementation can more easily be swapped out.
