setns.2: It is possible to setns() to the caller's current PID namespace
The page currently incorrectly says that 'fd' must refer to
a descendant PID namespace. However, 'fd' can also refer to
the caller's current PID namespace. Verified by experiment,
and also comments in kernel/pid_namespace.c (Linux 5.8-rc1).
