Thanks for pointing it out; I'm not sure if it's the same thing
Christian noticed but I believe what I had applied with his suggestion
of initializing i worked either way... But this is moot since I updated
to v4 afterwards:
this v4 has been merged in 6.7-rc7 as follow:
https://git.kernel.org/linus/ff49bf1867578f23a5ffdd38f927f6e1e16796c4
(the message-id also points to the v4 correctly, e.g.
https://lkml.kernel.org/r/20231206200913.16135-1-pchelkin@ispras.ru )
Thanks,
