If a probe is attached to a static function that is in multiple files with the same name, removing it by name will remove all instances: # grep jump_label_unlock set_ftrace_filter jump_label_unlock:traceoff:unlimited jump_label_unlock:traceoff:unlimited # echo '!jump_label_unlock:traceoff' >> set_ftrace_filter # grep jump_label_unlock set_ftrace_filter # But the loop in reset_ftrace_filter will try to remove multiple instances multiple times. If this happens the second time will error and cause the test to fail. At each iteration of the loop, check to see if the probe being removed still exists.

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.
