Lustre has a 'struct ptlrpc_thread' which provides control functionality wrapped around kthreads. None of the functionality used in statahead.c requires ptlrcp_thread - it can all be done directly with kthreads. So discard the ptlrpc_thread and just use a task_struct directly. One particular change worth noting is that in the current code, the thread performs some start-up actions and then signals that it is ready to go. In the new code, the thread is first created, then the startup actions are perform, then the thread is woken up. This means there is no need to wait any more than kthread_create() already waits.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
