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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.

The PCI hotplug core has just been refactored to separate slot initialization for in-kernel use from publication to user space. Take advantage of it in pciehp by publishing to user space last on probe. This will allow enable/disablement of the slot exclusively from the IRQ thread because the IRQ is requested after initialization for in-kernel use (thereby getting its unique name needed by the IRQ thread) but before user space is able to submit enable/disable requests. On teardown, the order is the same in reverse: The user space interface is removed prior to freeing the IRQ and destroying the slot. Signed-off-by:Lukas Wunner <lukas@wunner.de> Signed-off-by:
