Good afternoon!

Since which kernel versions (NFS server, NFS client) is NFSv4.2
READ_PLUS safely usable?

Linux 6.2 for the server side and 6.6 for the client.

Also, could you make this a mount option, so people can turn this
on/off per mount, instead of using a kernel build option for this?

The eventual plan is to remove the kernel build option entirely. We
probably won't do a mount option, and just have it enabled by default
when using NFS v4.2.

Anna, I'm still planning on either re-sending the patch you wrote to
enable/disable optional features per-mount, or re-work it to make it
file-per-feature as the sysfs creators intended.

We need the option to toggle client's default per-server or per-mount.
