Yes, thanks to this thread. There is real communication problems.
Developers / maintainers are too busy to continue threads on my patches.
Let's see several examples.

Example 1: (not a problem with linux-next only patch, but a communication problem)

  Linus's "None of this makes any sense." comment at
  https://lkml.kernel.org/r/CAHk-=wjmFiptPgaPx9vY3RG=rqO452UmOAPb1y_f9GQBtuJVjg@xxxxxxxxxxxxxx
  made Mikulas to say "I don't know what else to do." at
  https://lkml.kernel.org/r/290bd5eb-9638-53ce-3c71-23b996d6ba54@xxxxxxxxxx , causing
  https://lkml.kernel.org/r/329e1951-0704-4d90-aeeb-ffc7123f4262@xxxxxxxxxxxxxxxxxxx and
  https://lkml.kernel.org/r/9a05e50c-75c1-4452-b40f-f5a8b487f3ed@xxxxxxxxxxxxxxxxxxx to stall.
  We need clarification from Linus or response from Mikulas.

Example 2: (a problem with moving from linux-next only patch to networking patch, but a communication problem)

  I responded to Jakub's "Have you see netdev_hold() / netdev_put() ?" comment at
  https://lkml.kernel.org/r/20260325192214.133ffaaf@xxxxxxxxxx but got no response.
  I need clarification or response from Jakub. If some core maintainer asks network
  people "Let's update all existing dev_put()/dev_hold() users to use netdev_put()/
  netdev_hold()", some progress would be made. No progress as long as no response.

Example 3: (a problem with linux-next only patch, but a communication problem)

  I responded to Al's "Not a peep in the logs, breakage still there" comment at
  https://lkml.kernel.org/r/ebceac56-6a65-4918-b47c-1fb87aa66989@xxxxxxxxxxxxxxxxxxx
  but got no response. Therefore, I sent an updated version
  https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit?id=3ae78a69d3a9a4ad1d3b267324bd742654f40965
  to linux-next, and I am currently waiting for syzbot to reproduce this problem.
