    Subject[PATCH] bluetooth cmtp: Convert to use kthread API.
    Date
    From: Eric W. Biederman <ebiederm@xmission.com>

    This patch modifies the kcmptd_ctr_%d daemon using kthread_run
    instead of a combination of kernel_thread and daemonize making
    the code a little simpler and more maintainable.
