163 	If this is set, then the callback will only be called by functions
174 Filtering which functions to trace
177 If a callback is only to be called from specific functions, a filter must be
196 Filters denote which functions should be enabled when tracing is enabled.
197 If @buf is NULL and reset is set, all functions will be enabled for tracing.
199 The @buf can also be a glob expression to enable all functions that
210 To add more functions, call the ftrace_set_filter() more than once with the
212 with new functions defined by @buf, have @reset be non-zero.
214 To remove all the filtered functions and trace all functions:
232 If a glob is used to set the filter, functions can be added to a "notrace"
233 list that will prevent those functions from calling the callback.
235 two lists are non-empty and contain the same functions, the callback will not
238 An empty "notrace" list means to allow all functions defined by the filter
247 functions it finds to not be traced. This is a separate list from the

260 functions should call the callback, it is best to set the filters before
265 matching glob to functions, the switch will happen during the time of
266 the ftrace_set_filter() call. At no time will all functions call the callback.
