'add_list' sounds the most natural and some of the\nrelated variables also use 'add' such as 'add_size'.\n\nTo reduce variation, rename 'added' and 'add_head' to 'add_list'.\nAlso rename some 'realloc_head' cases selectively to 'add_list'.\n\nWhile it would be nice to rename every 'realloc_head' to 'add_list' for\nconsistency, it might create a backport headache with all to work going\ninto this algorithm that may need to be eventually backported. Thus,\nit's better to leave 'realloc_head' as is for now.\n\nSigned-off-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>\n---\n drivers/pci/pci.h | 2 +-\n drivers/pci/setup-bus.c | 26 +++++++++++++-------------\n 2 files changed, 14 insertions(+), 14 deletions(-)", "diff": "diff --git a/drivers/pci/pci.h b/drivers/pci/pci.h\nindex 4a14f88e543a..4fcf5a25ad9e 100644\n--- a/drivers/pci/pci.h\n+++ b/drivers/pci/pci.h\n@@ -515,7 +515,7 @@ int pci_dev_res_add_to_list(struct list_head *head, struct pci_dev *dev,\n void __pci_bus_size_bridges(struct pci_bus *bus,\n \t\t\tstruct list_head *realloc_head);\n void __pci_bus_assign_resources(const struct pci_bus *bus,\n-\t\t\t\tstruct list_head *realloc_head,\n+\t\t\t\tstruct list_head *add_list,\n \t\t\t\tstruct list_head *fail_head);\n bool pci_bus_clip_resource(struct pci_dev *dev, int idx);\n void pci_walk_bus_locked(struct pci_bus *top,\ndiff --git a/drivers/pci/setup-bus.c b/drivers/pci/setup-bus.c\nindex 4cf120ebe5ad..3765693e95f0 100644\n--- a/drivers/pci/setup-bus.c\n+++ b/drivers/pci/setup-bus.c\n@@ -756,13 +756,13 @@ static void __assign_resources_sorted(struct list_head *head,\n }\n \n static void pdev_assign_resources_sorted(struct pci_dev *dev,\n-\t\t\t\t\t struct list_head *add_head,\n+\t\t\t\t\t struct list_head *add_list,\n \t\t\t\t\t struct list_head *fail_head)\n {\n \tLIST_HEAD(head);\n \n \tpdev_sort_resources(dev, &head);\n-\t__assign_resources_sorted(&head, add_head, fail_head);\n+\t__assign_resources_sorted(&head, add_list, fail_head);\n \n }\n \n@@ -1502,13 +1502,13 @@ static void pdev_assign_fixed_resources(struct pci_dev *dev)\n }\n \n void __pci_bus_assign_resources(const struct pci_bus *bus,\n-\t\t\t\tstruct list_head *realloc_head,\n+\t\t\t\tstruct list_head *add_list,\n \t\t\t\tstruct list_head *fail_head)\n {\n \tstruct pci_bus *b;\n \tstruct pci_dev *dev;\n \n-\tpbus_assign_resources_sorted(bus, realloc_head, fail_head);\n+\tpbus_assign_resources_sorted(bus, add_list, fail_head);\n \n \tlist_for_each_entry(dev, &bus->devices, bus_list) {\n \t\tpdev_assign_fixed_resources(dev);\n@@ -1517,7 +1517,7 @@ void __pci_bus_assign_resources(const struct pci_bus *bus,\n \t\tif (!b)\n \t\t\tcontinue;\n \n-\t\t__pci_bus_assign_resources(b, realloc_head, fail_head);\n+\t\t__pci_bus_assign_resources(b, add_list, fail_head);\n \n \t\tswitch (dev->hdr_type) {\n \t\tcase PCI_HEADER_TYPE_BRIDGE:\n@@ -1613,19 +1613,19 @@ void pci_bus_claim_resources(struct pci_bus *b)\n EXPORT_SYMBOL(pci_bus_claim_resources);\n \n static void __pci_bridge_assign_resources(const struct pci_dev *bridge,\n-\t\t\t\t\t struct list_head *add_head,\n+\t\t\t\t\t struct list_head *add_list,\n \t\t\t\t\t struct list_head *fail_head)\n {\n \tstruct pci_bus *b;\n \n \tpdev_assign_resources_sorted((struct pci_dev *)bridge,\n-\t\t\t\t\t add_head, fail_head);\n+\t\t\t\t add_list, fail_head);\n \n \tb = bridge->subordinate;\n \tif (!b)\n \t\treturn;\n \n-\t__pci_bus_assign_resources(b, add_head, fail_head);\n+\t__pci_bus_assign_resources(b, add_list, fail_head);\n \n \tswitch (bridge->class >> 8) {\n \tcase PCI_CLASS_BRIDGE_PCI:\n@@ -2303,7 +2303,7 @@ static int pbus_reassign_bridge_resources(struct pci_bus *bus, struct resource *\n \tunsigned long type = res->flags;\n \tstruct pci_dev_resource *dev_res;\n \tstruct pci_dev *bridge = NULL;\n-\tLIST_HEAD(added);\n+\tLIST_HEAD(add_list);\n \tLIST_HEAD(failed);\n \tunsigned int i;\n \tint ret = 0;\n@@ -2337,10 +2337,10 @@ static int pbus_reassign_bridge_resources(struct pci_bus *bus, struct resource *\n \tif (!bridge)\n \t\treturn -ENOENT;\n \n-\t__pci_bus_size_bridges(bridge->subordinate, &added);\n-\t__pci_bridge_assign_resources(bridge, &added, &failed);\n-\tif (WARN_ON_ONCE(!list_empty(&added)))\n-\t\tpci_dev_res_free_list(&added);\n+\t__pci_bus_size_bridges(bridge->subordinate, &add_list);\n+\t__pci_bridge_assign_resources(bridge, &add_list, &failed);\n+\tif (WARN_ON_ONCE(!list_empty(&add_list)))\n+\t\tpci_dev_res_free_list(&add_list);\n \n \tif (!list_empty(&failed)) {\n \t\tif (pci_required_resource_failed(&failed, type))\n", "prefixes": [ "02/11" ] }
