Subject: sas_scsi_host: partially convert to use the kthread API
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
This patch modifies the sas scsi host thread startup to use kthread_run not
kernel_thread and deamonize. kthread_run is slightly simpler and more
maintainable.
akpm: the driver should also be converted to use kthread_should_stop() and
kthread_stop().
