Subject: [PATCHv3 for-next 0/4] New multipath policy for RTRS client
Date: Wed,  7 Apr 2021 13:34:40 +0200	[thread overview]
Message-ID: <20210407113444.150961-1-gi-oh.kim@ionos.com> (raw)

This patch set introduces new multipath policy 'min-latency'.
The latency is a time calculated by the heart-beat messages. Whenever
the client sends heart-beat message, it checks the time gap between
sending the heart-beat message and receiving the ACK. So this value
can be changed regularly.
If client has multi-path, it can send IO via a path having the least
latency.

V3->V2: use sysfs_emit instead of scnprintf
V2->V1: use sysfs_emit instead of sprintf

  RDMA/rtrs-clt: new sysfs attribute to print the latency of each path
  Documentation/ABI/rtrs-clt: Add descriptions for min-latency policy
