Bug Description
SRU Justification
[Impact]
Microsoft has requested the addition of 2 module parameters to sunrpc. The primary purpose of which is to restrict or pin NFSv3 TCP connections to one server in order to take advantage of local server connection caching. In the presence of a load balancer, round robin connection requests defeats the advantages of local caching.
[Test Plan]
Microsoft tested
[Where things could go wrong]
NFSv3 connection attempts could be slow or fail altogether.
