[PATCH v3 0/6] exit: Put an upper limit on how often we can oops

[Kees Cook <keescook@xxxxxxxxxxxx>]

Hi,

This builds on Jann's v1 patch[1]. Changes in v3:
- fix #if/#ifdef confusion (Bill)
- rename from "reason" or "origin" and add it to the warn output (Marco)

v2: https://lore.kernel.org/lkml/20221109194404.gonna.558-kees@xxxxxxxxxx/

Thanks,

-Kees
