Please let me know how to patch it without getting failed.

Start with ptosc-patch/0001-ptosc-square-changes.patch, the target file 3.0, and the generated 3.0.rej file; compare the three failed hunks with the latest pt-online-schema-change 3.0.13 source. Done means the patch applies without failed hunks and no reject file is produced.
