The real work will be identifying any/all spin locking that currently exists. For all of those, the code needs to change to: 1. trylock if oops_in_progress, otherwise spinlock 2. if trylock fails, the code must have a sane failure The 2nd point will be the difficult one. For example, you may have functions without a return value taking spinlocks. But now those functions could fail.
