Subject: Re: [RFC v2 PATCH 00/13] HARDENED_ATOMIC
Done. I added a line to the "HARDENED_ATOMIC Implementation" section
of Documentation/security/hardened-atomic.txt describing the results
of the benchmarks (no measurable performance difference). You might
want to add this line to the cover letter as well.
I know I promised to post the results of another set of benchmarks I
performed, and I will do that soon.
Thanks,
David
