From aa3fe714f70654da47d9c2659b2d9ee295a9d930 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Thu, 12 Sep 2013 14:57:27 +0200 Subject: block: Assert validity of BdrvActionOps In qmp_transaction, assert that the BdrvActionOps to be used is actually valid. This assertion failing is very improbable, however, it might happen, if a new TransactionActionKind is introduced "out of order" and the actions[] array is not updated.
