Subject: [PATCH 0/7] libtracfes: Add tracefs_function_filter()
Date: Mon, 22 Mar 2021 21:27:55 -0400
Message-ID: <20210323012755.155237800@goodmis.org> (raw)

This adds a new API tracefs_function_filter() as described in:

 https://bugzilla.kernel.org/show_bug.cgi?id=210643

It will use regular expressions against available_filter_functions (or even
the kernel glob expression) to enable the function by the index method if it
is supported. If it is not supported, it will go back to the writing of the
filter strings directly into the set_ftrace_filter file.
