From a24ba4644b7ae5af3cd2eb6992c237cb4548c45e Mon Sep 17 00:00:00 2001 From: Javier González Date: Mon, 28 Nov 2016 22:38:56 +0100 Subject: lightnvm: export set bad block table MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bad blocks should be managed by block owners. This would be either targets for data blocks or sysblk for system blocks. In order to support this, export two functions: One to mark a block as an specific type (e.g., bad block) and another to update the bad block table on the device. Move bad block management to rrpc.
