I'm less confident about libxl_cpupoolinfo_list_* than about topology
and numa info handling via libxl, but I suspect this is something
similar to what I just said in my reply to 12/28 ("libxl: only free
cputopology if it was allocated in libxl__get_numa_candidate").
That is to say, this does not look necessary to me, as
libxl_cpupoolinfo_list_free() seems to cope well with a non-allocated
prt, and making it like this deviates from the usual libxl exit
pattern/error handling style.
Thoughts?
Regards,
Dario
