[PATCH] nfsd to unlock kernel before exiting

From: Steven Rostedt
Date: Wed Aug 17 2005 - 13:26:12 EST


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.
