Subject: [PATCH 13/25] lightnvm: move the pages per block check out of the loop
Date: Tue, 12 Jan 2016 07:49:27 +0100 [thread overview]
Message-ID: <1452581379-18162-14-git-send-email-m@bjorling.me> (raw)
In-Reply-To: <1452581379-18162-1-git-send-email-m@bjorling.me>
From: Wenwei Tao <ww.tao0320@gmail.com>
There is no need to check whether dev's pages per block is
beyond rrpc support every time we init a lun, we only need
to check it once before enter the lun init loop.
