Thanks for the clear explanation. Part of my confusion before was that I mistakenly thought that the v2 struct added a padding field but this is not correct. The only thing that has changed is the number of debug regs.

We send one `user_watch_state` to the kernel, but in v2 this may contain 14 instead of 8. This is a common technique I've also seen it done on AArch64 for expanding register sets.
