From: Matthieu CASTET Date: Wed, 22 Aug 2012 14:03:46 +0000 (+0200) Subject: UBI: erase free PEB with bitflip in EC header X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=193819cf2e6e395b1e1be2d36785dc5563a6edca;p=linux-beck.git UBI: erase free PEB with bitflip in EC header 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).
