*
|
|
* 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.
|
|
*
|
|
* print: 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 "print" method.
|

* Note, that for both the assign and the print, __entry is the handler

|
*
|
|
* CFLAGS_trace-events-sample.o := -I$(src)
|
|

|
|
* This will make sure the current path is part of the include

*
|
|
* CFLAGS_trace-events-sample.o := -I$(PWD)
|
|

|

*
|
|
* #define TRACE_INCLUDE_PATH samples/trace_events
