Since Linux v2.4 it has been possible to stop all NFS server by running
rpc.nfsd 0
i.e. by requesting that zero threads be running. This is preferred as
it doesn't risk killing some other process which happens to be called
"nfsd".
Since Linux v6.6 - and other stable kernels to which
Commit: 390390240145 ("nfsd: don't allow nfsd threads to be
signalled.")
has been backported - sending a signal no longer works to stop nfs server
threads.
This patch changes the nfsserver script to use "rpc.nfsd 0" to stop
server threads.

Is this suppose to apply to the Linux nfs-utils upstream repo?
A bit confused...
