If a process inside a network namespace calls readlink() on /proc/pid/fd/n (for any pid) then the returned string is prefixed by "/root".
So you get "/root/sys/console" or "/root/var/log/fred" etc.
There seems to be an extra call to prepend_name() called from prepend_path() from d_path().
This seems decidedly wrong, especially since /root usually exists.
Even it is were reporting a file outside a chroot (opened before the chroot) prepending "/root" would be wrong.
Kernel is 5.10.132 (LTS before the retbleed breakages!)
