From bdc5f06789c5a0c3a9a2c0eb33ec4d177dbdaa22 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 17 May 2010 10:01:05 +0200 Subject: [PATCH] UBI: Fix problem in UBI/Linux "compatibility layer" "down_write_trylock" needs to return 1 instead of 0 for success. Otherwise copying a block with a read error (e.g. bit-flip on read) won't work correctly.
