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.

[Other Info]

SF: #00312346

This bug is awaiting verification that the linux-azure/5.4.0-1070.73 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
