KTHREAD_CREATE_ON_NO(9)                   Driver Basics                   KTHREAD_CREATE_ON_NO(9)



NAME
       kthread_create_on_node - create a kthread.

SYNOPSIS
       struct task_struct * kthread_create_on_node(int (*threadfn) (void *data), void * data,
                                                   int node, const char namefmt[], ...);

ARGUMENTS
       threadfn
           the function to run until signal_pending(current).

       data
           data ptr for threadfn.

       node
           task and thread structures for the thread are allocated on this node

       namefmt[]
           printf-style name for the thread.

       ...
           variable arguments

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. The new thread has SCHED_NORMAL policy
       and is affine to all CPUs.

       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 NUMA_NO_NODE. 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) or ERR_PTR(-EINTR).
