Thanks Konstantin! I did some minor cosmetic changes, extended a bit the documentation and improved the ipv4_tcp.with_fs test. You can see these changes in my -next branch: https://git.kernel.org/pub/scm/linux/kernel/git/mic/linux.git/log/?h=next We have a very good test coverage and I think these patches are ready for mainline. If it's OK with you, I plan to send a PR for v6.7-rc1 .
