From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx> Since acpiphp_check_bridge() called by acpiphp_check_host_bridge() does things that require PCI rescan-remove locking around it, make acpiphp_check_host_bridge() use that locking. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx> --- One more thing I overlooked in the PCI rescan-remove locking patchset. I just found it sitting there in a dark dusty corner and staring at me in horror when I approached it with a vacuum cleaner ... Anyway, 3.14-rc2 material on top of patches [1-2/13] from this series: https://lkml.org/lkml/2014/2/1/123 Thanks, Rafael --- drivers/pci/hotplug/acpiphp_glue.c | 4 ++++ 1 file changed, 4 insertions(+) Index: linux-pm/drivers/pci/hotplug/acpiphp_glue.c =================================================================== --- linux-pm.orig/drivers/pci/hotplug/acpiphp_glue.c +++ linux-pm/drivers/pci/hotplug/acpiphp_glue.c @@ -829,7 +829,11 @@ void acpiphp_check_host_bridge(acpi_hand bridge = acpiphp_handle_to_bridge(handle); if (bridge) { + pci_lock_rescan_remove(); + acpiphp_check_bridge(bridge); + + pci_unlock_rescan_remove(); put_bridge(bridge); } } -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
