For debugging the allocation of unused or potentially leaked interrupt descriptor it's helpful to have some information about the site which allocated them. In case of MSI this is simple because the caller hands the device struct pointer into the domain allocation function. Duplicate the device name and show it in the debugfs entry of the interrupt descriptor.

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.
