How about creating a function that frees exactly one
virResctrlMonitorStatsPtr and then (possibly) have a wrapper that
would call it 1 to n times? We can then get rid of this ugly call.
How about change virResctrlMonitorFreeStats to: (function name have been
changed to
virResctrlMonitorStatsFree)
```code
void
virResctrlMonitorStatsFree(virResctrlMonitorStatsPtr stat)
{
if (!stat)
return;
VIR_FREE(stat->vals);
virStringListFree(stat->features);
VIR_FREE(stat); /* Free virResctrlMonitorStats object */
}
```
And following code to is the way to free a list of
@virResctrlMonitorStatsPtr objects:
```code
static void
qemuDomainFreeResctrlMonData(virQEMUResctrlMonDataPtr resdata)
{
...
size_t i = 0;
for ( i = 0; i < resdata->nstats; i++)
virResctrlMonitorStatsFree(resdata->stats[i]);
virResctrlMonitorStatsFree
...
}
Yes, this is exactly what I had on mind.
