@Steve0x2a Unless a PR fixes a critical bug, we do not recommend PR cherry-pick to too many earlier versions. PTAL and choose the appropriate versions. Thanks.

[Steve0x2a]

@shichun-0415 OK, I made my choice based on previous relevant pr. What do you think about choosing master and v5.4? Or just master?

[shichun-0415]

@Steve0x2a I think master and v5.4 are fine.
