There were good intentions for proposing\n it, but it's not necessary anymore for the pciehp case at hand and\n it introduces risks by conflating what is actually affected when you\n request a slot reset.\n\n * Fixed up some typos, added requested code comments\n\n * Fixed up the compilation linking mistake in patch 1\n\n * I changed a parameter name in the last patch for the common bridge\n reset method. Previously called \"masked\", but it's really the case\n that both methods want to mask hotplug events. The real difference\n between thw two options is whether we save+restore the affected\n devices. The error handling path doesn't want that because the error\n handler is responsible for it. But everyone else wants the reset\n handler to take care of it automatically.\n\n * Added reviews\n\nKeith Busch (3):\n pci: rename __pci_bus_reset and __pci_slot_reset\n pci: allow all bus devices to use the same slot\n pci: make reset_subordinate hotplug safe\n\n drivers/pci/hotplug/pciehp_core.c | 3 +-\n drivers/pci/pci-sysfs.c | 3 +-\n drivers/pci/pci.c | 94 ++++++++++++++++++++-----------\n drivers/pci/pci.h | 2 +-\n drivers/pci/slot.c | 27 +++++++--\n include/linux/pci.h | 8 ++-\n 6 files changed, 96 insertions(+), 41 deletions(-)" }
