    Description

      A dangerous timeframe exists after enabling a NRS policy where setting a policy-specific tuning would lead to crashes, due to incomplete initialization of the policy.

      Trivial reproducer:
      echo -n orr > /proc/fs/lustre/ost/OSS/ost_io/nrs_policies & sleep 0.1 && echo -n 32 > /proc/fs/lustre/ost/OSS/ost_io/nrs_orr_quantum
