nfsd41: CREATE_EXCLUSIVE4_1
Implement the CREATE_EXCLUSIVE4_1 open mode conforming to
http://tools.ietf.org/html/draft-ietf-nfsv4-minorversion1-26
This mode allows the client to atomically create a file
if it doesn't exist while setting some of its attributes.
It must be implemented if the server supports persistent
reply cache and/or pnfs.
