Merge branch 'some-modifications-to-optimize-code-readability'

Li Zetao says:

====================
Some modifications to optimize code readability

This patchset is mainly optimized for readability in contexts where size
needs to be determined. By using min() or max(), or even directly
removing redundant judgments (such as the 5th patch), the code is more
consistent with the context.
