Thanks for the improvements, however we are mostly at the end of
development period for v6.8 kernel. Let me postpone applying the patches
until closing the next merge window (for v6.9), since we need the term to
evaluate the change. I mean that it goes to v6.10 kernel.
If you would like me to applying the patch v6.9 kernel, please inform it
to us.
Thanks
Takashi Sakamoto
