Subject: [PULL 22/33] qmp: Fix tracing of non-string command IDs
Date: Sat, 19 Dec 2020 11:55:21 +0100 [thread overview]
Message-ID: <20201219105532.1734134-23-armbru@redhat.com> (raw)
In-Reply-To: <20201219105532.1734134-1-armbru@redhat.com>
Tracepoints monitor_qmp_cmd_in_band and
monitor_qmp_cmd_out_of_band (commit cf869d5317 "qmp: support
out-of-band (oob) execution") treat non-string "id" like absent "id".
Fix that.
Signed-off-by: Markus Armbruster <armbru@redhat.com>
