Alexander Lobakin says: ==================== net: consolidate page_is_pfmemalloc() usage page_is_pfmemalloc() is used mostly by networking drivers to test if a page can be considered for reusing/recycling. It doesn't write anything to the struct page itself, so its sole argument can be constified, as well as the first argument of skb_propagate_pfmemalloc(). In Page Pool core code, it can be simply inlined instead. Most of the callers from NIC drivers were just doppelgangers of the same condition tests. Derive them into a new common function do deduplicate the code. Resend of v3 [2]: - it missed Patchwork and Netdev archives, probably due to server-side issues. Since v2 [1]: - use more intuitive name for the new inline function since there's nothing "reserved" in remote pages (Jakub Kicinski, John Hubbard); - fold likely() inside the helper itself to make driver code a bit fancier (Jakub Kicinski); - split function introduction and using into two separate commits; - collect some more tags (Jesse Brandeburg, David Rientjes). Since v1 [0]: - new: reduce code duplication by introducing a new common function to test if a page can be reused/recycled (David Rientjes); - collect autographs for Page Pool bits (Jesper Dangaard Brouer, Ilias Apalodimas).

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.
