NAME
trace_printk - printf formatting in the ftrace buffer
SYNOPSIS
trace_printk(fmt, args...);
ARGUMENTS
fmt the printf format for printing args... variable arguments
NOTE
__trace_printk is an internal function for trace_printk and the ip is passed in via the trace_printk macro. This function allows a kernel developer to debug fast path sections that printk is not appropriate for. By scattering in various printk like tracing in the code, a developer can quickly see where problems are occurring. This is intended as a debugging tool for the developer only. Please refrain from leaving trace_printks scattered around in your code.
