Subject: vsock/virtio: Rename virtio_vsock_alloc_skb()
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2304c64a2866c58534560c63dc6e79d09b8f8d8d;p=thirdparty%2Fkernel%2Flinux.git

vsock/virtio: Rename virtio_vsock_alloc_skb()

In preparation for nonlinear allocations for large SKBs, rename
virtio_vsock_alloc_skb() to virtio_vsock_alloc_linear_skb() to indicate
that it returns linear SKBs unconditionally and switch all callers over
to this new interface for now.

No functional change.
