In the code of the entire USB-storage module, the most soul part is in a function called usb_stor_control_thread (), which is naturally the climax of our entire story. Some special functions are called from the usb_stor_acquire_resources () function, which we will see soon. It only appears once in the whole play, that is, in storage_probe, where the row number is 1005. However, before that, there were four functions in front of us, namely get_device_i

it simply, when kthread_create () is executed, there will be two processes: one is the parent process and the other is the child process. The child process will execute usb_stor_control_thread (), while us serves as the parameter (real parameter) of the usb_stor_control_thread function, after executing usb_stor_control_thread (), the sub-process ends and it will call the exit () function to exit. The parent process continues to follow the usb_stor_acquire_resources () function. For the parent p

to track the parent and child processes separately. First look at the parent process, line 1: 811 wake_up_process (th ); To wake up a sub-process, you need to wake up the sub-process because it will not be executed immediately after you create a sub-process using kthread_create (). it will not be executed until you wake up, therefore, this function is equivalent to the voice of the referee in the track and field. The athlete will not start running
