The shrinker_map may be touched from any cpu (e.g., a bit there may be set by a task running everywhere) but kswapd is always bound to specific node. So allocate shrinker_map from the related NUMA node to respect its NUMA locality. Also, this follows generic way we use for allocation of memcg's per-node data.

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.
