Hi Yinghai,
Good points! It's safe with current implementation because
all root bus hotplug operations are under protection of
pci_remove_rescan_mutex.

The function pci_create_root_bus() allocates the pci bus structure,

for a pci root bus will be set by function pci_scan_child_bus().
If a pci root bus is destroyed before calling pci_scan_child_bus(),
the is_added flag will not be set.
how that can be met?
Do we have pci_remove_rescan_mutex around them?
