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
memory node number.
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.
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).
