The current comment is confusing because if global or memcg deferred list in the second tail page is occupied by compound_head, why we still use page[2].deferred_list here? I think it wants to say that Global or memcg deferred list in the first tail page is occupied by compound_mapcount and compound_pincount so we use the second tail page's deferred_list 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.
