When the process is aware of how to handle, why does it transfer control flow to the kernel?

edit

The kernel is responsible for managing and coordinating low-level hardware resources, such as memory, CPU, and input/output devices, which are essential for the proper functioning of the system. When a process requests access to these resources, it needs to interact with the kernel to perform the necessary actions, such as allocating memory or reading/writing data from/to a file. Therefore, even if the process is aware of how to handle a particular task, it still needs to transfer control flow to the kernel to execute the low-level operations required to complete the task. Additionally, the kernel also provides security and protection mechanisms to prevent unauthorized access or modification of system resources, which is another reason why control flow needs to be transferred to the kernel.
