Let me CC live-patching ML, because from a quick glance this is something

which "sympos" is based on.

In a quick skim, it looks like the symbol resolution is using
kallsyms_on_each_symbol(), so I think this is safe? What's a good
selftest for live-patching?


Hi Kees,

I don't think any of the in-tree tests currently exercise the kallsyms/sympos end of livepatching.

I do have a local branch that does facilitate creating klp-relocations that do rely upon this feature -- I'll try to see if I can get those working with this patchset and report back later this week.
