So that is the bug in the Linux kernel. Since fixing kernel is much easier

Fixing a bug in the Linux kernel is not "much easier". You are taking
a purely engineering viewpoint, but life is not like that. There are
lots of copies of Linux kernels around and in use. The issue is not
fixing the kernel per se, it is propagating that change to all
Linux kernels in use -- THAT'S another matter entirely, and is
far far more difficult than making sure that a kernel fix is
qualified and widely proopagated.


Not really, it's just a matter of time. Typical distro cycles are on the order of 3 years.

again, in the real world, there are MANY projects that are nothing like this interactive when it comes to moving to new versions of operating systems.
