Subject: [PATCH-for-5.2 v2 17/25] block/nvme: Set request_alignment at initialization
Date: Thu, 29 Oct 2020 10:32:58 +0100 [thread overview]

In-Reply-To: <20201029093306.1063879-1-philmd@redhat.com>
Commit bdd6a90a9e5 ("block: Add VFIO based NVMe driver")
sets the request_alignment in nvme_refresh_limits().
For consistency, also set it during initialization.
