Hi Mike > My question was why do you call to alloc_constrained in the dump_header() > function rather than pass the constraint that was detected a bit earlier to > that function? dump_header will be called by three functions: oom_kill_process, check_panic_on_oom, out_of_memory. We can get the constraint from the last two functions(check_panic_on_oom, out_of_memory), but I need to pass a new parameter(constraint) for oom_kill_process. Thanks
