DESCRIPTION¶
This helper function creates and names a kernel thread. The thread will be stopped: use wake_up_process to start it. See also kthread_run. If thread is going to be bound on a particular cpu, give its node in node, to get NUMA affinity for kthread stack, or else give -1. When woken, the thread will run threadfn() with data as its argument. threadfn() can either call do_exit directly if it is a standalone thread for which no one will call kthread_stop, or return when ' kthread_should_stop' is true (which means kthread_stop has been called). The return value should be zero or a negative error number; it will be passed to kthread_stop. Returns a task_struct or ERR_PTR(-ENOMEM).COPYRIGHT¶
