I do not see how one can effectively use skb_insert() without holding some kind of lock. Otherwise other cpus could have changed the list right before we have a chance of acquiring list->lock. Only existing user is in drivers/infiniband/hw/nes/nes_mgt.c and this one probably meant to use __skb_insert() since it appears nesqp->pau_list is protected by nesqp->pau_lock. This looks like nesqp->pau_lock could be removed, since nesqp->pau_list.lock could be used instead.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
