Byungchul Park says: ==================== Split netmem from struct page The MM subsystem is trying to reduce struct page to a single pointer. See the following link for your information: https://kernelnewbies.org/MatthewWilcox/Memdescs/Path The first step towards that is splitting struct page by its individual users, as has already been done with folio and slab. This patchset does that for page pool. Matthew Wilcox tried and stopped the same work, you can see in: https://lore.kernel.org/20230111042214.907030-1-willy@infradead.org I focused on removing the page pool members in struct page this time, not moving the allocation code of page pool from net to mm. It can be done later if needed. ==================== Link: https://patch.msgid.link/20250721021835.63939-1-byungchul@sk.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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 reStructuredText 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.
