  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
