This is comparable to other reservation schemes. Yes, but it's a reservation scheme that doesn't show up in MemFree, for instance. Even hugetlbfs-reserved memory subtracts from that. This has the potential to be really confusing to apps. If this memory is now not available to normal apps, they might plow into the invisible memory limits and get into nasty reclaim scenarios. Shouldn't this subtract the memory for MemFree and friends? -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
