I'm not sure I see that interface defined in the kernel. As far as I remember the guid_t is used solely inside kernel by Hyper-V code and the rest is using raw buffers. Can you point out to the specific place(s)? > As I didn't see a 0/4 for this series, I'm confused as to your end-goal > here. What are you trying to do with this series? End goal is to decouple internal type, which is guid_t, from ABI, where should be something else in use, like __u8[16] or so. We have two internal types, i.e. uuid_t and guid_t that are differs by byte ordering (when represented as human-readable string). uuid_t is provided by libuuid in the user space and its definition may be quite different to what we have inside kernel. Kernel already hide that one. guid_t is a leftover. I will create a cover letter for next version. -- With Best Regards, Andy Shevchenko
