From: Boris Brezillon Date: Fri, 16 Sep 2016 14:59:12 +0000 (+0200) Subject: UBI: fastmap: scrub PEB when bitflips are detected in a free PEB EC header X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ecbfa8eabae9cd73522d1d3d15869703c263d859;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git UBI: fastmap: scrub PEB when bitflips are detected in a free PEB EC header scan_pool() does not mark the PEB for scrubing when bitflips are detected in the EC header of a free PEB (VID header region left to 0xff). Make sure we scrub the PEB in this case.
