Hi Darrick, xfs guys and btrfs guys. Although such question is quite late as reflink generic tests are in fstests for a long time, I'm still not sure what's the correct behavior for reflink len = 0. Test case generic/182 is causing different output between btrfs and xfs. For btrfs, dedupe will just return 0 and check nothing, while for xfs len == 0 means to check the whole file length. Both makes sense for me, for btrfs len = 0 behavior, it just follows read/write functions. And I assume xfs follows reflink behavior, when len is not specified, then reflink the length of src file. But since it's a generic test, we need to unify the behavior. So, which one is the standard and which document should we follow for such behavior definition?
