Hello:

This patch was applied to netdev/net.git (refs/heads/master):

On Fri, 29 Jan 2021 23:53:50 +0000 you wrote:
AF_RXRPC sockets use UDP ports in encap mode.  This causes socket and dst
from an incoming packet to get stolen and attached to the UDP socket from
whence it is leaked when that socket is closed.

When a network namespace is removed, the wait for dst records to be cleaned
up happens before the cleanup of the rxrpc and UDP socket, meaning that the
wait never finishes.
