tr = graph_array

246

ftrace_graph_addr_finish(trace)

248

If trace_recursion_test(TRACE_GRAPH_NOTRACE_BIT) Then

249

trace_recursion_clear(TRACE_GRAPH_NOTRACE_BIT)

250

Return

254

cpu = These macros fold the SMP functionality into a single CPU system()

255

data = per_cpu_ptr(data, cpu)

disabled = atomic_inc_return( & disabled)

257

If Value is more likely to compile time(disabled == 1) Then

258

pc = We mask the PREEMPT_NEED_RESCHED bit so as not to confuse all current users* that think a non-zero value indicates we cannot preempt.
