From 3a8fa0ed3e1a8dc54f9297d2a2292b87e03e21b5 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Sun, 22 Aug 2010 21:27:30 +0300 Subject: UBIFS: improve error reporting when reading bad node When an error happens during validation of read node, the typical situation is that the LEB we read is unmapped (due to some bug). It is handy to include the mapping status into the error message.
