| A -- NO --> STOP | ||
| A -- YES --> A1{Approved<br> for 202205<br> Branch?} | ||
| A1 -- NO --> STOP | ||
| A1 -- YES --> A2(pr_cherrypick_prestep) | ||
| B(pr_cherrypick_prestep) | ||
| B --> B1{cherry pick<br>conflict?} | ||
| B1 -- YES --> B2(Add tag:<br>Cherry Pick Confclit_202205) --> B3(Add comment:<br>refer author code conflict) --> STOP1(STOP) | ||
| B1 -- NO --> B4(Create New PR) -- success --> B5(New PR add tag:<br> automerge) --> B6(New PR add comment:<br>Origin PR link) --> B7(Origin PR add tag:<br>Created PR to 202205 Branch) --> B8(Origin PR add comment:<br>New PR link) | ||
| B4 -- fail --> STOP1 | ||
| ``` | ||
|
