[PATCH RFC net-next v4 06/12] vsock/virtio: use the global netns
From: Bobby Eshleman <hidden>
Date: 2025-08-05 21:49:22
Also in:
kvm, linux-hyperv, linux-kselftest, lkml, virtualization
Subsystem:
networking [general], the rest, virtio and vhost vsock driver, virtio core, vm sockets (af_vsock) · Maintainers:

From: Bobby Eshleman <redacted> This changes virtio-vsock to always use the global netns dummy so that all guest vsock continues to operate in global mode. The guest vsock behavior is unchanged.
