This should be static I think.
As the code stands now, I don't think so. It is defined in
xend_internal.c but used in xen_internal.c
A bigger problem here is that I think the call to xenDaemonNodeGetInfo
should happen inside
xen_internal.c:xenHypervisorNodeGetCellsFreeMemory, something like this:
xenHypervisorNodeGetCellsFreeMemory (virConnectPtr conn, ....)
{
static int nb_nodes = -1;
if (nb_nodes == -1) {
virNodeInfo info;
if (xenDaemonNodeGetInfo (conn, &info) == -1) {
... (error) ...
}
nb_nodes = info->nodes;
}
...
}
Note also the explicit test for == -1
I like this solution. I thought that Daniel wanted it out of the
xenHypervisorNodeGetCellsFreeMemory call, and in some init code. Daniel?
Do you have an opinion on this?
The rest of the patch looks OK to me.
Rich.
