  "message": "block: Allow wait_serialising_requests() at any point\n\nWe can only have a single wait_serialising_requests() call per request\nbecause otherwise we can run into deadlocks where requests are waiting\nfor each other. The same is true when wait_serialising_requests() is not\nat the very beginning of a request, so that other requests can be issued\nbetween the start of the tracking and wait_serialising_requests().\n\nFix this by changing wait_serialising_requests() to ignore requests that\nare already (directly or indirectly) waiting for the calling request.\n\nSigned-off-by: Kevin Wolf \u003ckwolf@redhat.com\u003e\nReviewed-by: Max Reitz \u003cmreitz@redhat.com\u003e\nReviewed-by: Benoit Canet \u003cbenoit@irqsave.net\u003e\n",
