I think it is better to goto closelog
Yeah, I think so before, but 'closelog' label will free 'buf', in fact,
we haven't successfully allocate
buf is inited to NULL, so it is safe to use VIR_FREE(buf)
Agree, will send v2 patch based on your advice.
memory to 'buf' variable, I'm not sure whether it is a issue. maybe, the
above is a simple way, otherwise, it should be better if we add a check
for 'buf' variable in 'closelog' label, it looks like this:
...
if (buf)
VIR_FREE(buf);
If buf is NULL, VIR_FREE(bus) does nothing and is safe.
If you add a check for 'buf', make syntax-check will fail.
Thanks.
