From 1b1f9a9d00447d9eab32ae5633f60a106196b75f Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 17 May 2010 10:00:51 +0200 Subject: [PATCH] UBI: Ensure that "background thread" operations are really executed The current U-Boot UBI implementation is copied from Linux. In this porting the UBI background thread was not handled correctly. Upon write operations ubi_wl_flush() makes sure, that all queued operations, like page-erase, are completed. But this is missing for read operations. This patch now makes sure that such operations (like scrubbing upon bit-flip errors) are not queued, but executed directly.
