vsock/virtio: Allocate nonlinear SKBs for handling large transmit buffers (2025-07-17 08:33:09 -0400)
Oh no I am sorry! Please ignore, a bad commit snuck in there - it still needs maintainer approval, and I forgot. Will resend.
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
