*
* If the header name will be different than the system name
* (as in this case), then you can override the header name that

*
* This file is called trace-events-sample.h but we want the system
* to be called "sample". Therefore we must define the name of this
* file:
*
* #define TRACE_INCLUDE_FILE trace-events-sample
*
* As we do an the bottom of this file.
*
* Notice that TRACE_SYSTEM should be defined outside of #if
* protection, just like TRACE_INCLUDE_FILE.

* The TRACE_EVENT macro is broken up into 5 parts.

* name: name of the trace point. This is also how to enable the tracepoint.
* A function called trace_foo_bar() will be created.
*
* proto: the prototype of the function trace_foo_bar()
* Here it is trace_foo_bar(char *foo, int bar).
*
* args: must match the arguments in the prototype.
* Here it is simply "foo, bar".
*
* struct: This defines the way the data will be stored in the ring buffer.
* There are currently two types of elements. __field and __array.
* a __field is broken up into (type, name). Where type can be any
* type but an array.
* For an array. there are three fields. (type, name, size). The
* type of elements in the array, the name of the field and the size
* of the array.
*
* __array( char, foo, 10) is the same as saying char foo[10].
*
* fast_assign: This is a C like function that is used to store the items
* into the ring buffer.
*
* printk: This is a way to print out the data in pretty print. This is
* useful if the system crashes and you are logging via a serial line,
* the data can be printed to the console using this "printk" method.
*
* Note, that for both the assign and the printk, __entry is the handler
* to the data structure in the ring buffer, and is defined by the
* TP_STRUCT__entry.

* #define TRACE_INCLUDE_PATH samples/trace_events
