No, I wonder why code a loop when a simple memset() does the same.

There are other such cryptic markers - eventually from some doc
generating tool.

If you already have a struct, then drop these duplication.

Such duplication of information is just a source of errors. And
asm-offsets.h has been provided exactly for the purpose to avoid such
