New Revision: 317275
URL: https://svnweb.freebsd.org/changeset/base/317275
Log:
Don't create a backchannel for a DS connection.
An NFSv4.1 client connection to a Data Server (DS) should not have a
backchannel. This patch fixes the NFSv4.1/pNFS client to not do a backchannel
for this case.
Found during recent testing with the pNFS server under development.
