However, it's possible for a netdev to\nbe unregistered without going through that: When the netns that\nholds the wiphy is destroyed, the wiphy is supposed to move to\nthe init_ns, but that can run into allocation failures.\n\nThen, mac80211 has an interface listed that doesn't exist, and\nwill eventually hit\n\n  BUG: failure at net/wireless/core.h:141/wiphy_to_rdev()!\n  ...\n
