No, we want to run the function only if the previous one has not failed (in other words, stop running the initcalls as soon as one fails). The macro acts on the caller's 'ret' variable, which is not good practice, I know. > > Something like > #define INITCALL(_call) \ > do { \ > int _ret; _ret = _call(); \ > if (!ret) \ > debug("%s(): calling %s() failed\n", __func__, #_call); \ > _ret; \ > } while (0) In fact, since the caller of initcall_run_f() will call hang() on error we may as well do it sooner: #define INITCALL(_call) \ do { \ if (_call()) { \ debug("%s(): calling %s() failed\n", __func__, \ #_call); \ hang(); \ } \ } while(0) I'll post a v2. Thanks for reviewing.
