Re: [Xen-devel] [PATCH net-next] xen-netback: correct length checks on hash copy_ops

> The length checks on the grant table copy_ops for setting hash key and
> hash mapping are checking the local 'len' value which is correct in
> the case of the former but not the latter. This was picked up by
> static analysis checks.
> This patch replaces checks of 'len' with 'copy_op.len' in both cases
> to correct the incorrect check, keep the two checks consistent, and to
> make it clear what the checks are for.
