I see the enable-delalloc-by-default-patch that quickly followed the delalloc-ext4-writeback mode. Does this mean that data=writeback mode must be used, and if this condition is met, then delalloc is enabled, or is delalloc enabled even if ordered data mode? Any clarification on this would be most appreciated. I am looking for the combination of features that give me the fastest ext4 system with reasonable data integrity. Gary
