Subject: [PATCH v2 0/8] vsock/virtio: SKB allocation improvements
Hello again,
Here is version two of the patches I previously posted here:
https://lore.kernel.org/r/20250625131543.5155-1-will@kernel.org
Changes since v1 include:
* Remove virtio_vsock_alloc_skb_with_frags() and instead push decision
to allocate nonlinear SKBs into virtio_vsock_alloc_skb()
* Remove VIRTIO_VSOCK_DEFAULT_RX_BUF_SIZE and inline its definition
along with a comment
* Validate the length advertised by the packet header on the guest
receive path
* Minor tweaks to the commit messages and addition of stable tags
Thanks to Stefano for all the review feedback so far.
Cheers,
Will
