Our contributions to the kernel at that time was PID, IPC, and network namespaces, with the last one being the biggest.<ref>[http://www.linuxfoundation.org/sites/main/files/publications/whowriteslinux.pdf Linux Kernel DevelopmentHow Fast it is Going, Who is Doing It, What They are Doing, and Who is Sponsoring It: An August 2009 Update]</ref>

* Jul 15, 2011: Pavel Emelyanov sent initial RFC and code<ref>[http://lwn.net/Articles/451916/ Checkpoint/restore mostly in the userspace]</ref>. The idea of CRIU of course came up earlier when we figured we (or anyone else, for that matter) can't possibly merge in-kernel checkpoint/restore. Re-implementing it in userspace looked crazy for everyone including me, and Andrew Morton's and Linus Torvalds' initial reaction was similar ("some crazy russians").* Sep 23, 2011: Cyrill Gorcunov made <ref>[https://github.com/xemul/criu/commit/523de236244946a0de127dfc9954369963819ef7 First commit to CRIU (Checkpoint and Restore in Userspace)]</ref> first commit to CRIU project
