[PATCH] D147707: Make BPF stack size overridable

Hello Alexei,
I appreciate your prompt attention. Determining the maximum stack size is difficult, but a reasonable estimate could be an increase of two orders of magnitude.
We developed a computational storage processor at the IT University of Copenhagen that executes eBPF programs. During our evaluation of loop versus loop-unrolling performance on hardware, we discovered that the stack is easily prone to exhaustion and that kernel characteristics no longer apply when executing on hardware.
We plan on conducting additional research to comprehend the characteristics of eBPF on computational storage.
