Kthread demo
WebThe kthread_add () function is used to create a kernel thread. The new thread runs in kernel mode only. It is added to the process specified by the procp argument, or if that is NULL, to proc0. The func argument specifies the function that the thread should execute. WebYou can use the rcutree.kthread_prio kernel boot parameter to increase the scheduling priority of RCU’s kthreads, which can help avoid this problem. However, please note that doing this can increase your system’s context-switch rate and thus degrade performance.
