Subject: [PULL 5/5] qapi: More complex uses of QAPI_LIST_APPEND
Date: Thu, 28 Jan 2021 08:45:06 +0100 [thread overview]
Message-ID: <20210128074506.2725379-6-armbru@redhat.com> (raw)
In-Reply-To: <20210128074506.2725379-1-armbru@redhat.com>
From: Eric Blake <eblake@redhat.com>
These cases require a bit more thought to review; in each case, the
code was appending to a list, but not with a FOOList **tail variable.
