I have a question about that. Are the dprints going to show the stack backtrace?
Otherwise how can I see which exact allocation failed and was not properly handled?

If yes above? then I'm not sure I like it either, because am I'll be getting a full
stack backtrace for every failed allocation?

But I might like it if I try. How do I turn on allocation failures prints?
Can I filter out to print only GFP_KERNEL failures and or other GFP combinations?

Thanks
