[v2,0/3] libtracefs: Introduce new API to reset ftrace instance

Message

Tzvetomir Stoyanov (VMware) April 26, 2023, 4:11 a.m. UTC

A new API tracefs_instance_reset() for resetting instance to its default
state, based on the logic from "trace-cmd reset" command.

v2 changes:
 - Check if the kernel is configured with triggers enabled, before calling
   clear_trigger().
 - Clear "stack_trace_filter" file.
 - Fixed spelling and coding style errors.
