I know I have been inconsistent on this myself in the past but recently I've been taking the attitude that the counters can be used to fit into some other metric. I'm looking to change the compaction counters to be able to build a basic cost model for example. The same idea could be used for balloons of course but it's a less critical path than compaction for THP for example. Assuming it builds and all the defines are correct when the feature is not configured (I didn't check) then there is nothing wrong with the patch. However, if it was dropped would it make life very hard or would you notice? -- Mel Gorman SUSE Labs _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
