Please review when you free, thank!

- add comments before the function definition. [Andra]
- rename several variables, parameters and function. [Andra]
Patch 2:
- update the commit title and commit message. [Andra]
- add comments before the function definition. [Andra]

the beginning of the function. [Andra]
- double sanity checking after the merge of physical contiguous
