Enabling and disabling of an interrupt involves several steps that can fail. Cleanup after failure is done when the error is encountered, resulting in some repetitive code. Support for dynamic contexts will introduce more steps during interrupt enabling and disabling. Transition to centralized exit path in preparation for dynamic contexts to eliminate duplicate error handling code.

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.
