Message-Id: <1460536072-1728-1-git-send-email-ww.tao0320@gmail.com> Date: Wed, 13 Apr 2016 16:27:50 +0800 From: Wenwei Tao <ww.tao0320@...il.com> To: mb@...htnvm.io Cc: linux-kernel@...r.kernel.org, linux-block@...r.kernel.org Subject: [PATCH 1/3] lightnvm: calculate rrpc total blocks and sectors up front Calculate rrpc total blocks and sectors up front, make sense to use them. For example, we use rrpc->nr_sects to calculate rrpc area size, but it makes no sense if we don't initialize it up front, since it would be zero until we finish rrpc luns init.
