Could have also gone with the removal of NONNULL in the prototype like I did. IDC whichever way is deemed "more appropriate"... Seeing as drv_name is only ever passed as QEMU_DRIVER_NAME, but dom_name is passed from 'name' which doesn't have the NONNULL on it, that's why I chose removing NONNULL from the prototype.

I think I prefer John's way too. (At least partly because I dislike ATTRIBUTE_NONNULL() and would like to see as many of them as possible go away). > > John > >> diff --git a/src/util/virhostdev.c b/src/util/virhostdev.c >> index 2c557f5bbc6b..998df5871539 100644 >> --- a/src/util/virhostdev.c >> +++ b/src/util/virhostdev.c >> @@ -2060,8 +2060,8 @@ virHostdevReAttachMediatedDevices(virHostdevManagerPtr mgr, >> continue; >> >> virMediatedDeviceGetUsedBy(tmp, &used_by_drvname, &used_by_domname); >> - if (STREQ_NULLABLE(drv_name, used_by_drvname) && >> - STREQ_NULLABLE(dom_name, used_by_domname)) { >> + if (used_by_drvname && STREQ(drv_name, used_by_drvname) && >> + used_by_domname && STREQ(dom_name, used_by_domname)) { >> VIR_DEBUG("Removing %s dom=%s from activeMediatedHostdevs", >> mdevsrc->uuidstr, dom_name); >> virMediatedDeviceListDel(mgr->activeMediatedHostdevs, tmp); >> > > -- > libvir-list mailing list > libvir-list@redhat.com > https://www.redhat.com/mailman/listinfo/libvir-list > -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list

But for that we'd have to reach a decision. However there are not only cons, some pros can be that the compiler is able to make better guesses or not have to be guessing at all. As a counter-argument, there are way more attribute we could use and we don't, plus libvirt is not the CPU hogger where we would have to go optimize so low. So while the answer is not clear, I wouldn't, as mentioned before, be against removing all such occurrences, maybe except public APIs, if someone happens to have a good reason for that. -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list

I see your commit from 2012 now. And I think we might consider removing attribute_nonnull altogether.
