Steven Rostedt c29f122cd7 ftrace: Add context level recursion bit checking ... Currently for recursion checking in the function tracer, ftrace tests a task_struct bit to determine if the function tracer had recursed or not. If it has, then it will will return without going further. But this leads to races. If an interrupt came in after the bit was set, the functions being traced would see that bit set and think that the function tracer recursed on itself, and would return. Instead add a bit for each context (normal, softirq, irq and nmi). A check of which context the task is in is made before testing the associated bit. Now if an interrupt preempts the function tracer after the previous context has been set, the interrupt functions can still be traced.
