This has not yet been observed, but conceivably, when using GFP_KERNEL allocations from drbd_md_sync(), drbd_flush_after_epoch() or receive_SyncParam(), we could trigger additional IO to our own device, or an other device in a criss-cross setup, and end up in a local deadlock, or potentially a distributed deadlock in a criss-cross setup involving the peer blocked in a similar way waiting for us to make progress.
