vsock/virtio: Allocate nonlinear SKBs for handling large transmit buffers (2025-07-17 08:33:09 -0400)
----------------------------------------------------------------
virtio, vhost: features, fixes
vhost can now support legacy threading
if enabled in Kconfig
vsock memory allocation strategies for
large buffers have been improved,
reducing pressure on kmalloc
vhost now supports the in-order feature
guest bits missed the merge window
fixes, cleanups all over the place
