Subject: [PATCH 0/3] NVMe multipath path selector enhancements
Date: Mon, 25 Sep 2023 12:31:20 -0400 [thread overview]
Message-ID: <20230925163123.16042-1-emilne@redhat.com> (raw)
This patch series adds a "queue-depth" iopolicy to the NVMe multipath
path selector code. It also adds the capability to optionally allow
the use of ANA nonoptimized paths as well as optimized paths, this can
be beneficial in some cases and helps to provide additional paths to
verify the desired target port utilization.
