commit: 193819cf2e6e395b1e1be2d36785dc5563a6edca From: Matthieu CASTET <[email protected]> Date: Wed, 22 Aug 2012 16:03:46 +0200 Subject: 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).
