As Trond Myklebust pointed out, the current kthread-based lockd and nfsv4 callback threads have a race condition if they are started and brought down very rapidly. If this occurs, there is a chance that the main thread function will never be run, and the cleanup done when the function exits will not occur. This patchset fixes this by moving the cleanup into the respective *_down functions. While Bruce has just taken in a patchset from me to change nfsd to kthreads, this race doesn't seem to exist there. We aren't using kthread_stop() to take down nfsd, only signals, so I don't think the kthread can be stopped before nfsd() actually runs. The set also includes a patch to remove the BKL from nfs_callback_up and nfs_callback_down.
