Sure. If a process wants to compare two namespaces, it needs to get file
descriptors for them (open /proc/PID/ns/XXX, use new ioctl-s, find a
process which has them),
and then it calls kcmp(pid1, pid2, KCMP_NSFD, ns_fd1, ns_fd2)
If you use the new ioctl-s to get ns_fd2, do you walk your local /proc
to find pid2?
