Subject: UBI: Change the default percentage of reserved PEB
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=54de1f1c44c3522dbdc2201be1f65e733526de51;p=deliverable%2Flinux.git

UBI: Change the default percentage of reserved PEB

The actual value (1%) is too low for actual NAND devices, a huge
majority of device has 2% maximum bad blocks (SLC or MLC).
(Actually it's 20 blocks on a 1024 blocks device, 40/2048...)
