  "message": "wifi: mac80211: do not abuse fq.lock in ieee80211_do_stop()\n\nlockdep complains use of uninitialized spinlock at ieee80211_do_stop() [1],\nfor commit f856373e2f31ffd3 (\"wifi: mac80211: do not wake queues on a vif\nthat is being stopped\") guards clear_bit() using fq.lock even before\nfq_init() from ieee80211_txq_setup_flows() initializes this spinlock.\n\nAccording to discussion [2], Toke was not happy with expanding usage of\nfq.lock. Since __ieee80211_wake_txqs() is called under RCU read lock, we\ncan instead use synchronize_rcu() for flushing ieee80211_wake_txqs().\n\nLink: https://syzkaller.appspot.com/bug?extid\u003deceab52db7c4b961e9d6 [1]\nLink: https://lkml.kernel.org/r/874k0zowh2.fsf@toke.dk [2]\nReported-by: syzbot \u003csyzbot+eceab52db7c4b961e9d6@syzkaller.appspotmail.com\u003e\nSigned-off-by: Tetsuo Handa \u003cpenguin-kernel@I-love.SAKURA.ne.jp\u003e\nFixes: f856373e2f31ffd3 (\"wifi: mac80211: do not wake queues on a vif that is being stopped\")\nTested-by: syzbot \u003csyzbot+eceab52db7c4b961e9d6@syzkaller.appspotmail.com\u003e\nAcked-by: Toke Høiland-Jørgensen \u003ctoke@kernel.org\u003e\nSigned-off-by: Kalle Valo \u003ckvalo@kernel.org\u003e\nLink: https://lore.kernel.org/r/9cc9b81d-75a3-3925-b612-9d0ad3cab82b@I-love.SAKURA.ne.jp\n[ pick up commit 3598cb6e1862 (\"wifi: mac80211: do not abuse fq.lock in ieee80211_do_stop()\") from -next]\nLink: https://lore.kernel.org/all/87o7xcq6qt.fsf@kernel.org/\nSigned-off-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\n",
