From 68e3226bd4e05c4be1f6286e4e708e1163ffa092 Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Wed, 8 Oct 2014 14:55:58 +0200 Subject: [PATCH] UBI: Fastmap: Make WL pool size 50% of user pool size Don't use a fixed size for the WL pool. Make it instead 50% of the user pool. We don't make it 100% as it is not as heavily used as the user pool.
