List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org Cc: Gerd Hoffmann This patch moves the displaystate callback calls for setting the cursor and the mouse pointer from spice server to qemu (iothread) context. This allows us to simplify locking.
