It's apparent that a number of distributions and their customers
remain on long-term stable kernels. We are aware of the scalability
problems and other bugs in NFSD in kernels between v5.4 and v6.1.

To address the filecache and other scalability problems in those
kernels, I'm preparing backported patches of NFSD fixes for several
popular LTS kernels. The backported commits are destined for the
official LTS kernel branches so that distributions can easily
integrate them into their products.

Once this effort is complete, Greg and Sasha will continue to be
responsible for backporting NFSD-related fixes from upstream into
the LTS kernels.

Here's a status update.

---

I've pushed the NFSD backports to branches in this repo:

https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git

If you are able, I encourage you to pull these, review them or try
them out, and report any issues or successes. I'm currently using
the NFS workflows in kdevops as the testing platform, but am
planning to include other tests.


LTS v5.15.y

Greg is currently working on releasing 5.15.154, which should
contain the full set of NFSD filecache backports.

You can find these patches in the "nfsd-5.15.y" branch in the above
repo.


LTS v5.10.y

This branch has been rebased on 5.10.214. No change here this week.
Once v5.15.y is complete, I will start work on this branch again in
earnest.

You can find these patches in the "nfsd-5.10.y" branch in the above
repo.
