I cannot make up my mind about the RFC patches 9 and 10 yet. Conceptually they seem sound but they are much more far reaching than the rest of the series. It would be nice if patches 1-8 could be treated in isolation with data on the number of extfrag events triggered, time spent in compaction and the success rate. Patches 9 and 10 are tricy enough that they would need data per patch where as patches 1-8 should be ok with data gathered for the whole series. -- Mel Gorman SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
