Now the two proper patches have been submitted to the upstream, I backported them to stable branch (and SLE15-SP6 branch for Leap 15.6). https://lore.kernel.org/r/c2eaaf79-600a-4162-b439-8dbd7e7033fd@gmail.com https://lore.kernel.org/r/0c8e67ea-6505-43d1-bd51-94e7ecd6e222@gmail.com For TW, it'll be likely included in 6.7.4 update kernel.
