Subject: [PATCH 2/2] vdpa_sim_blk: add support for FUA writes
Date: Wed, 21 Oct 2026 06:52:34 +0100	[thread overview]
Message-ID: <20261021055235.648957-3-afaria@redhat.com> (raw)
In-Reply-To: <20261021055235.648957-1-afaria@redhat.com>

Expose VIRTIO_BLK_F_REQ_FLAGS and VIRTIO_BLK_F_REQ_FLAGS_OUT_FUA to
drivers. The simulator is a ramdisk, so it handles FUA and non-FUA
writes in the same way.
