Subject: [RFC 0/2] block: export latency info for cgroups
Date: Wed,  4 Oct 2017 10:41:18 -0700	[thread overview]
Message-ID: <cover.1507138530.git.shli@fb.com> (raw)

From: Shaohua Li <shli@fb.com>

Hi,

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

Thanks,
Shaohua
