Stefan Hajnoczi ab61335025 block: drain from main loop thread in bdrv_co_yield_to_drain() ... For simplicity, always run BlockDevOps .drained_begin/end/poll() callbacks in the main loop thread. This makes it easier to implement the callbacks and avoids extra locks. Move the function pointer declarations from the I/O Code section to the Global State section for BlockDevOps, BdrvChildClass, and BlockDriver. Narrow IO_OR_GS_CODE() to GLOBAL_STATE_CODE() where appropriate. The test-bdrv-drain test case calls bdrv_drain() from an IOThread. This is now only allowed from coroutine context, so update the test case to run in a coroutine.
