  "message": "virtio-net: don\u0027t schedule delayed refill worker\n\nWhen we fail to refill the receive buffers, we schedule a delayed worker\nto retry later. However, this worker creates some concurrency issues.\nFor example, when the worker runs concurrently with virtnet_xdp_set,\nboth need to temporarily disable queue\u0027s NAPI before enabling again.\nWithout proper synchronization, a deadlock can happen when\nnapi_disable() is called on an already disabled NAPI. That\nnapi_disable() call will be stuck and so will the subsequent\nnapi_enable() call.\n\nTo simplify the logic and avoid further problems, we will instead retry\nrefilling in the next NAPI poll.\n\nFixes: 4bc12818b363 (\"virtio-net: disable delayed refill when pausing rx\")\nReported-by: Paolo Abeni \u003cpabeni@redhat.com\u003e\nCloses: https://lore.kernel.org/526b5396-459d-4d02-8635-a222d07b46d7@redhat.com\nCc: stable@vger.kernel.org\nSuggested-by: Xuan Zhuo \u003cxuanzhuo@linux.alibaba.com\u003e\nSigned-off-by: Bui Quang Minh \u003cminhquangbui99@gmail.com\u003e\nAcked-by: Michael S.
