Subject: [PATCH 16/18] lightnvm: pblk: use nvm_rq_to_ppa_list()
Date: Thu, 14 Mar 2019 17:04:26 +0100	[thread overview]
Message-ID: <20190314160428.3559-17-igor.j.konopko@intel.com> (raw)
In-Reply-To: <20190314160428.3559-1-igor.j.konopko@intel.com>

This patch replaces few remaining usages of rqd->ppa_list[] with
existing nvm_rq_to_ppa_list() helpers. This is needed for theoretical
devices with ws_min/ws_opt equal to 1.
