Hi Dmitry,

I'm on the way to answering you. I understand your worry and appreciate 
your sugguestion on the improvement. Since I'm not the original author, 
either, I also need to undestand what was the original intention. i.e. 
Why should the fasync_list of the smc socket be handed over to the clc 
socket? Is there a way to deal with the list prior to the fallback?

AIU, the syzbot's reports on whichever the original fixed or your last 
patch fixed are about the same issue. And both of the fixes seem not to 
solve the problem.  Instead of patches on patches, I'd prefer to find 
the root problem and solve it.

Thus, to the proposed patches from you guys (and back to the question at 
the beginning), if the fasyn_list should be handed over, I like the Wen 
Gu's patch more. Otherwise, I'd like yours more, but as you already 
underlied, it should be done in some other way

Thanks,
Wenjia
