has a side effect of enabling or disabling specific functions
to be traced. Echoing names of functions into this file
will limit the trace to only those functions.
+ This influences the tracers "function" and "function_graph"
+ and thus also function profiling (see "function_profile_enabled").
The functions listed in "available_filter_functions" are what
can be written into this file.
Functions listed in this file will cause the function graph
tracer to only trace these functions and the functions that
they call. (See the section "dynamic ftrace" for more details).
+ Note, set_ftrace_filter and set_ftrace_notrace still affects
+ what functions are being traced.
set_graph_notrace:
This lists the functions that ftrace has processed and can trace.
These are the function names that you can pass to
- "set_ftrace_filter" or "set_ftrace_notrace".
+ "set_ftrace_filter", "set_ftrace_notrace",
+ "set_graph_function", or "set_graph_notrace".
(See the section "dynamic ftrace" below for more details.)
