Hmm, just FYI, I reworked this part in compatible patches set.
It will check iov.iov_len, returned by PTRACE_GETREGSET.
(It depends on compatible thread flag)
The same approach uses strace from 4.8 version:
https://sourceforge.net/projects/strace/files/strace/4.8/

So, this will be good, when patches set will made it's way to master.
