This is not exciting as Jeff Garzik's new NFSv4 server but a painful 
chore needs to be done. Will start to push the patches for NLM lock 
failover code next week. However, instead of doing large amount of 
patches all at once, would like to do it one by one, if they can be 
functionally separated. This is to avoid the tedious re-base works I 
have been doing for the past, (oh no), two years ??!!!

First one should be simple enough without too much explanation ....
