Usually static inline is avoided in .c files. Any special reason why
we'd need this especially much here? Those functions are pretty small
and I assume will be inlined anyway on most architectures.

I just did a test on x86_64 with GCC 11, and the same file was
produced with 'static' as with 'static inline'. Was there an
arch/config/compiler combo you were concerned about here?
