The replace_filter_string() frees the current string and then copies a given string. But in the two locations that it was used, the allocation happened right after the filter was allocated (nothing to replace). There's no need for this to be a helper function. Embedding the allocation in the two places where it was called will make changing the code in the future easier. Also make the variable consistent (always use "filter_string" as the name, as it was used in one instance as "filter_str") Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
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.
