When memory is a little tight on my system, it's pretty easy to see warnings that look like this. ksoftirqd/0: page allocation failure: order:3, mode:0x40a20(GFP_ATOMIC|__GFP_COMP), nodemask=(null),cpuset=/,mems_allowed=0 ... Call trace: dump_backtrace+0x0/0x1e8 show_stack+0x20/0x2c dump_stack_lvl+0x60/0x78 dump_stack+0x18/0x38 warn_alloc+0x104/0x174 __alloc_pages+0x588/0x67c alloc_rx_agg+0xa0/0x190 [r8152 ...] r8152_poll+0x270/0x760 [r8152 ...] __napi_poll+0x44/0x1ec net_rx_action+0x100/0x300 __do_softirq+0xec/0x38c run_ksoftirqd+0x38/0xec smpboot_thread_fn+0xb8/0x248 kthread+0x134/0x154 ret_from_fork+0x10/0x20 On a fragmented system it's normal that order 3 allocations will sometimes fail, especially atomic ones. The driver handles these failures fine and the WARN just creates spam in the logs for this case. The __GFP_NOWARN flag is exactly for this situation, so add it to the allocation. NOTE: my testing is on a 5.15 system, but there should be no reason that this would be fundamentally different on a mainline kernel.
