This is flawed. It's the irq that have to shrink the memory itself. It can't certainly reschedule kreclaimd and wait it to do the work. Increasing the free_pages_min limit is the _only_ alternative to having irqs that are able to shrink clean cache (and hopefully that "feature" will be resurrected soon since it's the only way to go right now).
