From: Sebastian Andrzej Siewior <bige...@linutronix.de> The usage of in_interrupt() in drivers in is phased out.
rtlwifi uses in_interrupt() in the RT_TRACE() debug macro which is sprinkled all over the driver. RT_TRACE() is almost identical to RTPRINT() which another hideous debug printk wrapper. The only difference is the printout of in_interrupt(). The decoding of in_interrupt() as hexvalue is non-trivial and aside of being phased out for driver use the return value is just by chance the masked preempt count value and not a boolean. These home brewn printk debug aids are tedious to work with and provide only minimal context. They should be replaced by trace_printk() or a debug tracepoint which automatically records all context information. To make progress on the in_interrupt() cleanup, make RT_TRACE() use the RTPRINT() debug function and remove _rtl_dbg_trace().
