Hi jiazhenyuan, The original commit 3256a2d6ab1f relay on commits 01a523b07161, 7ae189759cc4 and 9efdda4e3abe. The commits 7ae189759cc4 and 9efdda4e3abe solve the problems which are valuable. I think it is better to make a patchset including above commits to solve the problem. And, that can let openeuler codes has less difference with linux-stable as possible.
Thank you!
