Disable CONFIG_NFS_V4_2_READ_PLUS kernel config, as Linux kernel >= 6.6 enabled the CONFIG_NFS_V4_2_READ_PLUS config option by default, and nfs-ganesha version <= 6.1 is broken due to mishandling of the read_plus operation.

Do we want to reenable this CONFIG at some point? |
Maybe, I have not tried/found yet a nfs-ganesha version that fixes the issue, as it is not released yet, waiting for kubernetes-sigs/nfs-ganesha-server-and-external-provisioner#152 |
|
But even if the nfs-ganesha is fixed, as the possible fix landed a few days ago, it is safe to assume that we need to backport this change into the /stable/beta/alpha Flatcar versions. |

Manually checked on a two node K8S cluster that the issue is no longer present when CONFIG_NFS_V4_2_READ_PLUS=n.
