Hi, When running sctp_test from lksctp-tools in netns in 4.4 and 4.9 with suitable arguments, the local loopback device in the netns is not getting destroyed after deleting the netns.

Based on a quick test, 4.14 and 4.15 does not suffer from this, but its reproducible e.g. in 4.4.113 and 4.9.75 Any ideas?
By the versions you mentioned and report, maybe f186ce61bb82 ("Fix an
intermittent pr_emerg warning about lo becoming free.") fixed it.
