[PATCHv3 for-next 0/4] New multipath policy for RTRS client

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

 



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
