Sorry for the confusion. Thank you for clarifying. Here is our test:
We installed linux-5.4.0-156.173 (focal) from -proposed and tested it out with
good results. Ran test script on a mounted nfs share. Silly little test
(test.sh seen below):
#!/bin/bash
nfsstat -l | grep access
touch myfiles.
According to
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2022098, a patched
gke kernel was released to revert the default behavior and add the
nfs_fasc module parameter. linux-5.4.0-154.171 was proposed, but not
released. Can that be moved forward to fix this for impacted users?
