[nfsv4] Read delegations and LOCK operation

["Sandeep Joshi" <sjoshi at bluearc.com>]

From V4.1 protocol specification section 18.10.4. :

 

"When one or more clients hold read delegations, any LOCK request 
  where the server is implementing mandatory locking semantics, MUST
  result in the recall of all such delegations."

 

 

I have following question for above statement.

 

Why is the recall of read delegations necessary if the LOCK requested is a READ 
lock?

 

 

regards,
