"newpos" has wrong scope. It must be NULL on each iteration of the loop.
Otherwise, when policy is to be inserted at the start, we would instead
insert at point found by the previous loop-iteration instead.
Also, we need to unlink the policy before we reinsert it to the new node,
else we can get next-points-to-self loops.
Because policies are only ordered by priority it is irrelevant which policy
is "more recent" except when two policies have same priority.
(the more recent one is placed after the older one).
In these cases, we can use the ->pos id number to know which one is the
'older': the higher the id, the more recent the policy.
So we only need to unlink all policies from the node that is about to be
removed, and insert them to the replacement node.

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.
