I agree.

Though the most important takeaway for me is that this demonstrated the
problems which the kernel development has - once more.

What's worse is that it's known for quite some time that the kernel
development is understaffed and cannot keep up with the influx of
patches. Of course this has been willfully ignored - similar to other
completely avoidable horrors like the ssl disaster.

There is a long list of issues which lead to that situation, but let me
pick a few really important ones:

  - The 'features and performance first, correctness maybe' mentality in
    this industry.

  - The ignorance which takes the availability and sustainability of
    FOSS components especially "low-level plumbing" ones for granted,
    even if their business is built on and depends on these.

  - The unwillingness to put money on basic "low-level" technology just
    because it does not come with the 'hype-of-the-day' tag and is
    therefore useless for marketing and headlines.

None of these things can be solved at the technical level. There is no
technical solution which solves problems at the human stupidity and
even less so at the greed level.

While in theory the approach of sharing the workload for base technology
is obviously the right thing to do, the reality tells that sharing is
interpreted as make sure that someone else pays for it and I can push my
feature agenda.

As long as that does not change, nothing will change.

We can put technical countermeasures (as discussed elsewhere in this
thread) in place as much as we want, they are just futile attempts which
try to cure the symptoms.

As technical people we all know how useful the approach of curing the
symptoms instead of the root cause is. But still we try to do that
because we think it's our only option.

It's about time to rethink that approach.

Thanks,

        Thomas
