From 73a1a2298f3e9df24cea7a9aab412ba9470f6159 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Fri, 5 Feb 2021 11:50:02 -0800 Subject: [PATCH] nvme-multipath: set nr_zones for zoned namespaces The bio based drivers only require the request_queue's nr_zones is set, so set this field in the head if the namespace path is zoned.
