Hi greg k-h,
As a commercial Linux distribution maintainer, we understand that
even though upstream support for linux-4.19.y is ending, our users'
reliance on this kernel version will not cease immediately.
They often lack the time or resources to promptly migrate all their
devices to a newer kernel, due to considerations such as stability,
operational costs, and other factors.
Therefore, to provide a more graceful conclusion to the linux-4.19.y
lifecycle, we propose backporting these performance optimizations
to extend its useful life and ensure a smooth transition for commercial
users by the way.
Of course, we appreciate your suggestion and will prioritize backporting
these optimizations to linux-5.10.y and linux 5.4.y first.
Stay tuned for updates. We are committed to staying informed about kernel
updates and community trends. Thanks.
Sincerely,
