The nfsd holds the big kernel lock upon exit, when it really shouldn't. Not to mention that this breaks Ingo's RT patch. This is a trivial fix to release the lock.
Ingo, this patch also works with your kernel, and stops the problem with nfsd.
Note, there's a "goto out;" where "out:" is right above svc_exit_thread. The point of the goto also holds the kernel_lock, so I don't see any problem here in releasing it.
