A percpu script that needs an object handed to it by the runtime that started it, the quarantine set of the ifquarantine example, had no way to be given one: resume belonged to the plain runtime alone, so a script that takes its state that way could not be an instance per CPU. percpu:resume copies the objects into each instance and resumes it under the instance's lock, where it also reads the state, since an instance dispatches as soon as its script registers a hook and a stopped one has no state left. The error an instance raises is copied out under that lock and raised after it, naming the instance, because formatting it in place would allocate under a spinlock. lunatik_copyobjects and lunatik_resume lose their static to be reached from the percpu file.

A percpu script that needs an object from the runtime that started it, the quarantine set of the
ifquarantineexample, has no way to get one:resumebelongs to the plain runtime alone.percpu:resumecopies the objects into each instance and resumes it under the instance lock, where it also reads the state, since an instance dispatches as soon as its script registers a hook and a stopped one has no state left. Delivering the objects and resuming becomes one entry point,lunatik_resume, so that sequence is written once for both callers. Test:resume_percpu.Based on #799.
