Yes. Embedded people(at least, me) want it. That's because they don't have any swap device so they could reclaim only page cache page. And many page cache pages are mapped at address space of application(ex, android uses java model so many pages are mapped by application's address space). It means it's hard to reclaim them without lagging. So I have a interest in this patch. -- Kind regards, Minchan Kim -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
