Why these underscores?
It could be simply

[PATCH v2 00/16] add define guards to avoid multi-inclusion

[Weiguo Li]

Supplement define guards to prevent multiple inclusion.

Notice that there are couples of guard styles used in this project,
like "XX_H", "XX_H_" or "XXX_H__".
Adhere to Thomas's advice, this patch set use the first style to
make it simple.
