Subject: Re: Namespaced network devices not cleaned up properly after
execution of pmtu.sh kernel selftest
Linking in this thread as well - I submitted a patch to net-next with
a reproducer for just this bug. It works reliably on Grace/Grace on
v6.11 (and prior kernels already known to be affected), but I have not
had a chance to test it on other platforms yet. Let me know if I need
to adjust anything and whether it reproduces the bug on your machines.
Patch w/ reproducer:

Thanks!
