From c240b9af599d20e06a58090366be682684bd8555 Mon Sep 17 00:00:00 2001 From: aliguori Date: Sat, 28 Mar 2009 16:11:20 +0000 Subject: [PATCH] Fix vectored aio bounce handling immediate errors (Avi Kivity) If a bounced vectored aio fails immediately (the inner aio submission returning NULL) then the bounce handler erronously returns an aio request which will never be completed (and which crashes when cancelled). Fix by detecting that the inner request has failed and propagating the error.
