X-Received-From: 209.132.183.28 Cc: qemu-devel@nongnu.org Subject: [Qemu-devel] [PATCH 1/5] block: Rename bdrv_mon_event() & BlockMonEventAction X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org They are QMP events, not monitor events. Rename them accordingly. Also, move bdrv_emit_qmp_error_event() up in the file. A new event will be added soon and it's good to have them next each other.
