Subject: [PATCH 1/3] lightnvm: calculate rrpc total blocks and sectors up front
Date: Wed, 13 Apr 2016 16:27:50 +0800	[thread overview]
Message-ID: <1460536072-1728-1-git-send-email-ww.tao0320@gmail.com> (raw)

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.
