So the oom victim indeed passed the above force path after the oom

task is already killed! So what the hell is going on here.

I must be missing something obvious here.

YOU ARE OBVIOUSLY MISSING MY MAIL!

I already said this is "mm, oom: task_will_free_mem(current) should ignore MMF_OOM_SKIP for once."
problem which you are refusing at https://www.spinics.net/lists/linux-mm/msg133774.html .
And you again ignored my mail. Very sad...
