The statement no longer serves a purpose. Commitfa35864e0b("tuntap: Fix for a race in accessing numqueues") added the ACCESS_ONCE to avoid a race condition with skb_queue_len. Commit436accebb5("tuntap: remove unnecessary sk_receive_queue length check during xmit") removed the affected skb_queue_len check. Commit96f8406162("tun: add eBPF based queue selection method") split the function, reading the field a second time in the callee. The temp variable is now only read once, so just remove it.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
