How does kernel understand, which driver module function handles read/write/etc?
The answer to your question is struct file_operations. You will find it defined in both examples. This structure describes which function callbacks should be called (by providing pointers to those functions) when some operation on a file is performed (like a read, write or open). The pointer to this structure...
