With patches 1 and 2 the hang is Weird patch 2 makes the large order allocation without ~__GFP_WAIT, so even COMPACTION=y/n shouldn't matter anymore. Am I misreading something Mel? Removing ~__GFP_WAIT from patch 2 (and adding ~__GFP_REPEAT as a correctness improvement) and setting COMPACTION=y also should work ok. Removing ~__GFP_WAIT from patch 2 and setting COMPACTION=n is expected not to work well. But compaction should only make the difference if you remove ~__GFP_WAIT from patch 2. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
