TBH I'm slightly confused by this, and the previous warnings. The previous one was from a timer callback. This one is with BH disabled. I thought BH implies RCU protection. We certainly depend on that in NAPI for XDP. And threaded NAPI does the exact same thing as xfrm_trans_reinject(), a bare local_bh_disable(). RCU folks, did something change or is just holes in my brain again?
