Date: Wed, 30 Sep 2015 22:53:00 -0700 From: Yinghai Lu <yinghai@...nel.org> To: Bjorn Helgaas <bhelgaas@...gle.com>, David Miller <davem@...emloft.net>, Benjamin Herrenschmidt <benh@...nel.crashing.org>, Wei Yang <weiyang@...ux.vnet.ibm.com>, TJ <linux@....tj>, Yijing Wang <wangyijing@...wei.com> Cc: linux-pci@...r.kernel.org, linux-kernel@...r.kernel.org, Yinghai Lu <yinghai@...nel.org> Subject: [PATCH v6 26/53] PCI: Check if resource is allocated before trying to assign one In following alt_size support, we will call pci_assign_resource() several times on one resource list, and some resources could have been assigned already. Skip allocated resource in the list, as pci_assign_resource() only can handle not assigned resource.
