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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Shaohua Li <shli@xxxxxx>

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

V1->V2: improve the scalability

Shaohua Li (3):
  blk-stat: delete useless code
  block: set request_list for request
  blockcg: export latency info for each cgroup
