Linux Driver Board level file Tracking general method

/*********************************************************************************** * Linux Driver Board-level file tracking general method * Declaration: * 1. This is I use vim+ctags most commonly used tracking method, is also the only method;:) * 2. I have marked the tracking line on the track number, that is, sequential; * 3. For now, this approach seems to be universal; * 4. This example is just a simple demo, not all of it, and if you want to track it further, * keep going. * 5.
