Subject: [PATCH 15/15] block/nvme: Set request_alignment at initialization
Date: Wed, 14 Oct 2020 17:58:10 +0200	[thread overview]
Message-ID: <20201014155810.102841-16-philmd@redhat.com> (raw)
In-Reply-To: <20201014155810.102841-1-philmd@redhat.com>

When introducing this driver in commit bdd6a90a9e5
("block: Add VFIO based NVMe driver") we correctly
set the request_alignment in nvme_refresh_limits()
but forgot to set it at initialization. Do it now.
