Trond Myklebust 0afa6b4412 SUNRPC: Don't call __UDPX_INC_STATS() from a preemptible context ... Calling __UDPX_INC_STATS() from a preemptible context leads to a warning of the form: BUG: using __this_cpu_add() in preemptible [00000000] code: kworker/u5:0/31 caller is xs_udp_data_receive_workfn+0x194/0x270 CPU: 1 PID: 31 Comm: kworker/u5:0 Not tainted 4.15.0-rc8-00076-g90ea9f1 #2 Workqueue: xprtiod xs_udp_data_receive_workfn Call Trace: dump_stack+0x85/0xc1 check_preemption_disabled+0xce/0xe0 xs_udp_data_receive_workfn+0x194/0x270 process_one_work+0x318/0x620 worker_thread+0x20a/0x390 ? process_one_work+0x620/0x620 kthread+0x120/0x130 ? __kthread_bind_mask+0x60/0x60 ret_from_fork+0x24/0x30 Since we're taking a spinlock in those functions anyway, let's fix the issue by moving the call so that it occurs under the spinlock.
