[ Upstream commit 97fe22adf33f06519bfdf7dad33bcd562e366c8f ] Al Viro discovered a bug in the glob ftrace filtering code where "*a*b" is treated the same as "a*b", and functions that would be selected by "*a*b" but not "a*b" are not selected with "*a*b". Add tests for patterns "*a*b" and "a*b*" to the glob selftest.

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.
