From da105ed5fd7edcc5e0df7dbacef4dadda74e7ebe Mon Sep 17 00:00:00 2001 From: Joe Thornber Date: Fri, 27 Jul 2012 15:08:15 +0100 Subject: [PATCH] dm thin metadata: introduce dm_pool_abort_metadata Introduce dm_pool_abort_metadata to abort the current metadata transaction. Generally this will only be called when bad things are happening and dm-thin is trying to roll back to a good state for read-only mode. It's complicated by the fact that the metadata device may have failed completely causing the abort to be unable to read the old transaction. In this case the metadata object is placed in a 'fail' mode and everything fails apart from destroying it.
