hi,
I am working on the below API's
----------------------------------------------------
Add an API to set filtering of functions:
int tracefs_function_filter(struct tracefs_instance *instance, const
char *filter);
Which would write into the set_ftrace_filter file for the instance.
Also have a:
int tracefs_function_notrace(struct tracefs_instance *instance, const
char *filter);
That would write into the set_ftrace_notrace file for the instance.
Have a:
int tracefs_function_filter_clear(struct tracefs_instance *instance);
That clears the set_ftrace_filter file.
and a:
int tracefs_function_notrace_clear(struct tracefs_instance *instance);
That clears the set_ftrace_notrace file.
----------------------------------------------------------
Bugzilla link: https://bugzilla.kernel.org/show_bug.cgi?id=210643
if there is anyone already working on these API's please let me know.
Thanks,
sameer.

I don't believe anyone is currently working on this APIs. We're happy to
see patches for them coming from you.
