Hi,

Sure, it's OK for me. And I think if we call it *fs_size, maybe make the user
feel confused. The truth is it's the count of blocks, and only used for some
fs. So maybe we can call it *extra_opts, means used after device name?

So I will do this patch:

1. change tst_mkfs to 
void safe_mkfs(const int lineno, const char *fname, const char *dev,
               const char *fs_type, const char *const fs_opts[],
               const char *extra_opts)

2. add tst_mkfs into test.h:
static inline void tst_mkfs(const int lineno, const char *fname, const char *dev,
                             const char *fs_type, const char *const fs_opts[])
{
    safe_mkfs(lineno, fname, dev, fs_type, fs_opts, NULL);
}

Does this you want?

Thanks,
Zorro
