The whole thread is:
https://lore.kernel.org/linux-unionfs/20260623084337.54344-1-laoar.shao@gmail.com/T/#u

Personally, I feel offensive due to Yafang's expression
written above.  I keep maintain my replies in technical
discussion, but the replies above already include the
following words:

"No wonder containerd is getting harder and harder to use ;)"

"Please do your homework."

"Again, pls do your homework."

and the emotional texts `;)` make me feel uneasy over the
time,

especially the final words "I'll just go ahead and redirect
you to /dev/null ;)"

So I write an email as a public report to the CoC since I'm
not sure how to proceed to comment the community patches
because I could get offence as a result.

Thanks,
