Hi,
Unfortunately I cannot confirm that. Because the patch doesn't seem to
cover all cases of jumps. Please see the following comment for reference.
https://bugzilla.redhat.com/show_bug.cgi?id=1964036#c5
So I still see jumps when running a patched kernel. Though I'm under the
impression there are fewer jumps than without the patch.
Please be aware that I don't have any sophisticated test procedure. I'm
just using the TrackPoint during my work on different tasks and don't
have any reproducible test pattern, yet.

I could run an unpatched kernel for an hour and count the jumps. Then
run the patched version and count the jumps to see if there is
significant difference. Would that help to decide whether it's worth to
include the patch as a workaround or not?

Joerg
