Now that I think about this a bit more, we really have two different patterns here: 1. flush_tlb_mm_range() style, which is contiguous virtual address flushing from an unmap-style operation. 2. Mel's new try_to_unmap_one() style, which are going to be relatively random virtual addresses. So, the "ascending adjacent" case is still interesting, but it wouldn't cover Mel's new case. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
