From 00ee6cc3b74bdb4dfb71838046517beb6839647c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Matias=20Bj=C3=B8rling?= Date: Fri, 6 May 2016 20:03:09 +0200 Subject: [PATCH] lightnvm: refactor set_bb_tbl for accepting ppa list MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The set_bb_tbl takes struct nvm_rq and only uses its ppa_list and nr_pages internally. Instead, make these two variables explicit. This allows a user to call it without initializing a struct nvm_rq first.
