I have tried backporting this on 6.1.y and 5.15.y.

Here are the backports. (note: I would like to have them reviewed)

6.1.y: 
https://lore.kernel.org/all/20230825161603.371792-1-harshit.m.mogalapalli@xxxxxxxxxx/

5.15.y: 
https://lore.kernel.org/all/20230825161901.371818-1-harshit.m.mogalapalli@xxxxxxxxxx/


Thanks,
