the maintainer wants the patch to be verified in some distribution
first, if there is no regression, maybe he will merge the patch:


So I've discussed this with the Fedora kernel maintainers and they have
agreed to add the patch to the Fedora 5.15 kernels, which we will ask
our users to start testing soon (we first run some voluntary testing
before eventually moving all users over).

This will provide us with valuable feedback wrt this patch causing
regressions as you are worried about, or not.

Assuming no regressions show up I hope that this will give you
some assurance that there the patch causes no regressions and that
you will then be willing to pick this up later during the 5.16
cycle so that Fedora only deviates from upstream for 1 cycle.

Regards,

Hans
