This is another support module similar to livepatch-callbacks-mod.c.
I would use the same description, here:

MODULE_DESCRIPTION("Live patching demo for (un)patching callbacks, support module");

I've removed mentioning of NFS from the module description because
exportfs is now used for a lot more.

Applied to the vfs.fixes branch of the vfs/vfs.git tree.
Patches in the vfs.fixes branch should appear in linux-next soon.

Please report any outstanding bugs that were missed during review in a
new review to the original patch series allowing us to drop it.

It's encouraged to provide Acked-bys and Reviewed-bys even though the
patch has now been applied. If possible patch trailers will be updated.

Note that commit hashes shown below are subject to change due to rebase,

My past experience was to let individual maintainers take the ones that apply
