Hi Dave and Alex,

I saw this patch earlier from the stable list and was a little confused 
as to what the regression was (what exact hardware 
configurations/workloads one may observe this issue in?):

https://lore.kernel.org/stable/CADnq5_MPEwVGmnMBz_xzO4ZCBM0kgqP=rzwK+L5VPjwpnRj9+A@mail.gmail.com/

Since Alex commented that "End users care" about this regression on the 
stable list, I would really love to know what kind of regression we are 
looking at (and as distro maintainers, what we should be looking out 
for).

Alex, would you care to elaborate?

Best Regards,
Mingcong Bai
