struct tracer - a specific tracer and its callbacks to interact with debugfs
: called when one switches to this tracer (echo name > current_tracer) : called when one switches to another tracer : called when tracing is unpaused (echo 1 > tracing_enabled) : called when tracing is paused (echo 0 > tracing_enabled) : called when the trace file is opened : called when the trace_pipe file is opened : override how the user waits for traces on trace_pipe : called when the trace file is released : called when the trace_pipe file is released : override the default read callback on trace_pipe : override the default splice_read callback on trace_pipe : selftest to run on boot (see trace_selftest.c) : override the first lines that describe your columns : callback that prints a trace : signals one of your private flags changed (trace_options file) : your private flags
