Yes, your original set was very comprehensive, AFAICT. I'm not sure if
it'll apply to mainline well at this point, but I was definitely using
it as a guideline for what to do here.

The cover letter for the patchset that you sent out a few years ago had
a testcase in it. I was planning to use that to test once I start
broading this to other syscalls:
