Subject: [PATCH v9 02/11] PCI: Add root bus children dev's res to fail list
Date: Thu, 17 Jan 2013 23:53:13 -0800 [thread overview]
Message-ID: <1358495602-22867-3-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1358495602-22867-1-git-send-email-yinghai@kernel.org>
We can stop trying according to try_number now and do not need to use
root_bus checking as stop sign.
In extreme case we could need to reallocate resource for device just
under root bus. For pci root bus hot-add, we need to retry to assign
resources to pci devices just under pci root bus.
