Hi,
The commit 591a22c14d3f ("proc: Track /proc/$pid/attr/ opener mm_struct")
that we got in v5.13-rc6 broke our regression to pieces. The NIC interfaces
fail to start when using NetworkManager.
There is nothing in dmesg except error that NetworkManager failed to start.
Our setups are:
* VMs with virtio-net NICs
* Fedora 29
The revert fixes the issue and VMs boot with network working.
Thanks
