  "message": "cfg80211: check for and abort dangling scan requests\n\nIf you trigger a scan request on an interface and then\ntake it down, or rmmod the module or unplug the device\nthe driver might \"forget\" to cancel the scan request.\nThat is a bug in the driver, but the current behaviour\nis that we just hang endlessly waiting for the netdev\nrefcount to become 0 which it never will. To improve\nrobustness, check for this situation in cfg80211, warn\nabout it and clean up behind the driver. I don\u0027t just\nclean up silently because it\u0027s likely that the driver\nalso has some internal state it has now leaked.\n\nAdditionally, this fixes a locking bug, clearing the\nscan_req pointer should be done under the rdev lock.\n\nFinally, we also need to _wait_ for the scan work and\nnot just abort it since it might be pending and wanting\nto do a cleanup.\n\nSigned-off-by: Johannes Berg \u003cjohannes@sipsolutions.net\u003e\nSigned-off-by: John W.
