The nested field in struct gpio_irq_chip currently has two meanings. On one hand it marks an IRQ chip as being nested (as opposed to chained), while on the other hand it also means that an IRQ chip uses nested thread handlers. However, nested IRQ chips can already be identified by the fact that they don't pass a parent handler (the driver would instead already have installed a nested handler using request_irq()). Therefore, the only use for the nested attribute is to inform gpiolib that an IRQ chip uses nested thread handlers (as opposed to regular, non-threaded handlers). To clarify its purpose, rename the field to "threaded".

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
