How does this relate to the other PR #79470 (why comes this new patch when there is another for the same problem)?
I think it is better to first commit #79470, then add remaining functions `getc`, `putc`, `vfscanf`, `vfprintf`. These should be added anyway in a separate change because it is less related to invalidation.
