Mina Almasry says: ==================== Minor cleanups to skb frag ref/unref (part) This series is largely motivated by a recent discussion where there was some confusion on how to properly ref/unref pp pages vs non pp pages: https://lore.kernel.org/netdev/CAHS8izOoO-EovwMwAm9tLYetwikNPxC0FKyVGu1TPJWSz4bGoA@mail.gmail.com/T/#t There is some subtely there because pp uses page->pp_ref_count for refcounting, while non-pp uses get_page()/put_page() for ref counting. Getting the refcounting pairs wrong can lead to kernel crash.

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.
