Before the mdev enhancement type1 iommu used capable() to test the capability of current task; in the course of mdev development a new requirement, testing for another task other than current, was raised. ns_capable() was used for this purpose, however it still tests current, the only difference is, in a specified namespace. Fix it by using has_capability() instead, which tests the cap for specified task in init_user_ns, the same namespace as capable().

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.
