Subject: Re: [RFC PATCH v2 2/8] nvme: set BLK_FEAT_WRITE_ZEROES_UNMAP if
 device supports DEAC bit

I think you also need to add BLK_FEAT_WRITE_ZEROES_UNMAP to the list
of features supported by the nvme-mpath stacking driver in
nvme_mpath_alloc_disk, so that this gets propagated to multipathed
devices.

Otherwise this looks good to me.
