Previously, even if just one of the many fragments of a 9k packet required a copy, we'd copy the whole packet into a freshly-allocated 9k-sized linear SKB, and this led to performance issues. By having a pool of pages to copy into, each fragment can be independently handled, leading to a reduced incidence of allocation and copy.

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.
