I did one more pass yesterday and found some style issues and fixed them. The security review isn't done yet but any issues can be fixed during the 4.18 cycle. The ioctl structures look ok though I still don't feel I have a full understanding how the paths are constructed and if the buffers are big enough or what the limitations that can be hit in practice. The patchset will be added to misc-next and that's probably the last thing before I mark it as for-4.18 and will not touch until 4.18-rc1. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
