  "message": "Docs/admin-guide/cgroup-v2: document io.latency rotational vs non-rotational behavior\n\nio.latency is documented only in terms of average latency and the avg_lat\nstat, which matches rotational devices.  On non-rotational devices a group\nmisses its target once enough of the IOs in the window individually exceed\nit, and io.stat reports missed/total rather than avg_lat/win.\n\nDescribe both cases: how a miss is detected, note that the avg_lat tuning\nguidance is rotational-only, and update the io.stat field list (mark\navg_lat/win as rotational-only, document missed/total).\n\nAcked-by: Michal Koutný \u003cmkoutny@suse.com\u003e\nSigned-off-by: Tao Cui \u003ccuitao@kylinos.cn\u003e\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\n",
