We need to use kthread_create() here for a few reasons. First off to old kernel_thread() API functioin will be going away. Secondly, and more importantly if I use kthread_create() we can then properly implement a thread_exit() function which terminates the kernel thread at any point with do_exit(). This fixes our cleanup bug which was caused by dropping a mutex twice after thread_exit() didn't really exit. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@66 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c
