Description Denys Vlasenko 2020-01-24 16:24:09 UTC

We are going to be building rhel8 kernels for 10 years or more, more than one kernel build per day on average. We build them on rhel8 machines.
We would like to remove some easily fixable bottlenecks in the build process.

Please backport the fix from Fedora BZ 1773216 - these three commits:
