Agree. I posted a fixed patchset[1] before, maybe we can reconsider it.

For memoryless node, this patchset skip it and fallback to other nodes
when build its zonelists.
Mind resubmitting that to the MM folks, with the NULL dereference crash
mentioned prominently? Feel free to Cc: me.
OK, I will resend it if no one else objects. :)
Thanks,
Qi
Fixing hypothetical robustness problems is good, fixing specific crashes is
better. :-)
Thanks,
