From 04ed02cc7d431eb295bf9a4cb33c13319f34c48a Mon Sep 17 00:00:00 2001 From: Matthieu CASTET Date: Wed, 22 Aug 2012 16:03:46 +0200 Subject: [PATCH] UBI: erase free PEB with bitflip in EC header commit 193819cf2e6e395b1e1be2d36785dc5563a6edca upstream. Without this patch, these PEB are not scrubbed until we put data in them. Bitflip can accumulate latter and we can loose the EC header (but VID header should be intact and allow to recover data).
