Greg Kroah-Hartman has
a suggestion for anybody who would like to help him maintain
long-term-stable kernel releases. “All I request is that people test
the -rc releases when I announce them, and let me know if they work or not
for their systems/workloads/tests/whatever. […] But, if you want to do more,
I always really appreciate when people email me, or stable@vger.kernel.org,
git commit ids that are needed to be backported to specific stable kernel
trees because they found them in their testing/development efforts.“
