  "message": "block-coroutine-wrapper: Take AioContext lock in no_co_wrappers\n\nAll of the functions that currently take a BlockDriverState, BdrvChild\nor BlockBackend as their first parameter expect the associated\nAioContext to be locked when they are called. In the case of\nno_co_wrappers, they are called from bottom halves directly in the main\nloop, so no other caller can be expected to take the lock for them. This\ncan result in assertion failures because a lock that isn\u0027t taken is\nreleased in nested event loops.\n\nLooking at the first parameter is already done by co_wrappers to decide\nwhere the coroutine should run, so doing the same in no_co_wrappers is\nonly consistent. Take the lock in the generated bottom halves to fix the\nproblem.\n\nSigned-off-by: Kevin Wolf \u003ckwolf@redhat.com\u003e\nMessage-Id: \u003c20230525124713.401149-2-kwolf@redhat.com\u003e\nReviewed-by: Stefan Hajnoczi \u003cstefanha@redhat.com\u003e\nSigned-off-by: Kevin Wolf \u003ckwolf@redhat.com\u003e\n",
