Subject: [Qemu-devel] [PATCH 07/25] aio: test node->deleted before calling io_flush
Date: Fri, 26 Oct 2012 16:05:37 +0200 [thread overview]
Message-ID: <1351260355-19802-8-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1351260355-19802-1-git-send-email-pbonzini@redhat.com>
Otherwise, there could be a case where io_flush accesses freed
memory because it should not have been called.
