Hi Yongqiang, I'd like to hear back from Mingming and Allison about whether these patches conflict with their punch patches, since my understanding was they were planning on doing very similar things (and at least would be working in the very similar parts of the code). I agree that the extents code here could definitely use this cleanup, and I'm really glad that you worked on this; thank you! I just want to make sure work you are doing is coordinated with the work that Allison and Mingming are working on. - Ted -- 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
