A simple question about btrfs_ioctl_file_extent_same... Is there any check before btrfs_cmp_data is called that short-circuits things if the extents being compared are already the same extent? I was looking and could not find such a check, but I don't really know the btrfs source code that well. If there is no such check, would it not make sense to add one? -- Michael Welsh Duggan (md5i@md5i.com) -- 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
