Hi, the core of skinny-metadata feature has been merged in 3.10 (Jun 2013) and has been reportedly used by many people. No major bugs were reported lately unless I missed them. The obvious benefit is reduced metadata consumption at the cost of lost backward compatibility for pre-3.10 kernels. I believe this is acceptable to do the change now. The feature can be turned off at mkfs time by '-O ^skinny-metadata' if needed. I'd like to make it default with the 3.17 release of btrfs-progs. Please let me know if you have objections. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
