Cover letter [PATCH V2 0/3] block: export latency info for cgroups

From: Shaohua Li <[email protected]>

Hi,

latency info is a good sign to determine if IO is healthy. The patches export such info to cgroup io.stat.

I sent the first patch separately before, but since the latter depends on it, I include it here.

Thanks,
Shaohua
