We need a direct method of getting the pid inside containers.
If some issues occurred inside container guest, host user
could not know which process is in trouble just by guest pid:
the users of container guest only knew the pid inside containers.
This will bring obstacle for trouble shooting.

int getnspid(pid_t pid, int fd1, int fd2, int pidtype);

Please CC linux-api@vger.kernel.org on all patches that change the API
that the kernel presents to user space. See
https://www.kernel.org/doc/man-pages/linux-api-ml.html

Thanks,

Michael

Thanks for reminding.
