Toke Høiland-Jørgensen says: ==================== Fix late DMA unmap crash for page pool This series fixes the late dma_unmap crash for page pool first reported by Yonglong Liu in [0]. It is an alternative approach to the one submitted by Yunsheng Lin, most recently in [1]. The first commit just wraps some tests in a helper function, in preparation of the main change in patch 2. See the commit message of patch 2 for the details.

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.
