[PATCH v3 0/7] MR5912: win32u: Create a shared memory object for message queue and read active hooks bitmap from it.
-- v3: server: Remove now unnecessary active_hooks from replies. win32u: Remove now unnecessary thread info active_hooks cache. win32u: Read the active hooks count from the shared memory. server: Update the active hooks bitmaps when hooks are added / removed. server: Move hooks struct initialization within add_hook. server: Keep a reference on the desktop the hook are registered for. server: Create a thread message queue shared mapping.
