----------------------+----------------------------------------------------- There’s a race here because `fct_start` could be written before `startp`.
Should throw up some memory barriers or something.
{{{
static service_user *startp = NULL;
static void *fct_start = NULL;
…
if (fct_start == NULL &&
w.lookup(&startp, w.fct_name, &fct_start) != 0) {
*w.status = NSS_STATUS_UNAVAIL;
goto walk_nss_out;
}
}}}
