From 8a3c95ab385fb98621455807ae52b4454192f8c5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Javier=20Gonz=C3=A1lez?= Date: Mon, 28 Nov 2016 22:38:55 +0100 Subject: [PATCH] lightnvm: do not protect block 0 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Device blocks should be marked by the device and considered as bad blocks by the media manager. Thus, do not make assumptions on which blocks are going to be used by the device. In doing so we might lose valid blocks from the free list.
