I scanned through the patch, and didn't see any instances where we are
calling virCheckFlags after non-trivial work. It is something to be
aware of when using the macro in the future, since:
{
ptr *foo = somethingThatMallocs();
virCheckFlags(0, NULL);
would be a memory leak, masked because the return is hidden inside the
virCheckFlags macro.
But the alternative, of making virCheckFlags result in a bool, and
making all callers use:
if (virBadFlags(0))
return NULL;
is not as aesthetic. So:
ACK.
