that means it highely unlikey to get a fix for this issue :(
 
Yes, backporting just doest not suits for me.
 
I am trying to dig into the code, but really dont know if that's going to be that easy.
 
Thanks Eric for all the help.
W'll you know if I am able to fix this.
 
Thanks & Regards,
Amit Sahrawat

backporting xfs would be hard; I was hoping that perhaps you could just
boot a newer kernel, though I know w/ vendor arm kernels that can be tough.

There are drawbacks to not getting machine support upstream... :)

I don't really have other things for you to try, and don't have a lot of
time to debug 3 year old kernels either...  :(

You could try your arm testcase in a qemu emulator on a new kernel; if
that shows the same problem I'll be much more interested & motivated...
