Subject: ibmphp: partially convert to use the kthreads API
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
kthread_run replaces kernel_thread and dameonize.
allow_signal is unnecessary and has been removed. tid_poll was unused and
has been removed.
akpm: needs to be converted to use kthread_should_stop() and kthread_stop().
akpm: and mutexes!
