From ed4b7021cb51fe5a0f260df03298709347a26967 Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Mon, 3 Dec 2012 20:57:46 +0100 Subject: UBI: remove PEB from free tree in get_peb_for_wl() If UBI is built without fastmap, get_peb_for_wl() has to remove the PEB manially from the free tree. Otherwise the requested PEB lives in two trees.
