Hi all,

Here is version four of the patches I previously posted here:

  v1: https://lore.kernel.org/r/20250625131543.5155-1-will@kernel.org (local)
  v2: https://lore.kernel.org/r/20250701164507.14883-1-will@kernel.org (local)
  v3: https://lore.kernel.org/r/20250714152103.6949-1-will@kernel.org (local)

There are only two minor changes since v3:

  * Use unlikely() in payload length check on the virtio rx path

  * Add R-b tags from Stefano

Cheers,

Will

in my tree now. Let's see how does it go.
