E.g, consider the correct trace of the following sequence:\n\ndo_IRQ()\n{\n~\n irq_enter();\n~\n}\n\nTrace log (sample):\n\u003cidle\u003e-0 [00] 4154504455.781616: irq_enter \u003c- do_IRQ\n\nBut if irq_enter() has a kretprobe installed on it, the return value stored on the stack at each invocation is modified to divert the return to a kprobe trampoline function called kretprobe_trampoline(). So with this the trace would (currently) look like:\n\n\u003cidle\u003e-0 [00] 4154504455.781616: irq_enter \u003c- kretprobe_trampoline\n\nNow this is quite misleading to the end user, as it suggests something that didn\u0027t actually happen.
