From 4b79beb4c36d697e940e9f70d72399c71230a418 Mon Sep 17 00:00:00 2001 From: Wenwei Tao Date: Tue, 12 Jan 2016 07:49:27 +0100 Subject: [PATCH] lightnvm: move the pages per block check out of the loop MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
