Since callees (ip_rcv_core() and ip_rcv_finish_core()) might free or steal the skb, we can't use the list_cut_before() method; we can't even do a list_del(&skb->list) in the drop case, because skb might have already been freed and reused. So instead, take each skb off the source list before processing, and add it to the sublist afterwards if it wasn't freed or stolen.

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.
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.
