kobject: make kset_create check kobject_set_name return value

2009-06-16T04:30:24Z

kset_create should check the kobject_set_name return value. Add the return value checking code. Signed-off-by: Dave Young Signed-off-by: Greg Kroah-Hartman

driver: dont update dev_name via device_add path

2009-04-20T15:12:58Z

notice one system /proc/iomem some entries missed the name for pci_devices it turns that dev->dev.kobj name is changed after device_add. for pci code: via acpi_pci_root_driver.ops.add (aka acpi_pci_root_add) ==> pci_acpi_scan_root is used to scan pci bus/device, and at the same time we read the resource for pci_dev in the pci_read_bases, we have res->name = pci_name(pci_dev); pci_name is calling dev_name. later via acpi_pci_root_driver.ops.start (aka acpi_pci_root_start) ==> pci_bus_add_device to add all pci_dev in kobj tree. pci_bus_add_device will call device_add. actually in device_add /* first, register with generic layer. */ error = kobject_add(&dev->kobj, dev->kobj.parent, "%s", dev_name(dev)); if (error) goto Error; will get one new name for that kobj, old name is freed.

driver core: get rid of struct device's bus_id string array

2009-03-24T23:38:23Z

Now that all users of bus_id is gone, we can remove it from struct device. Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman

kobject: Cleanup kobject_rename and !CONFIG_SYSFS

2008-10-16T16:24:52Z

It finally dawned on me what the clean fix to sysfs_rename_dir calling kobject_set_name is. Move the work into kobject_rename where it belongs. The callers serialize us anyway so this is safe. Signed-off-by: Eric W. Biederman Acked-by: Tejun Heo Signed-off-by: Greg Kroah-Hartman

kobject: Fix kobject_rename and !CONFIG_SYSFS

2008-10-16T16:24:52Z

When looking at kobject_rename I found two bugs with that exist when sysfs support is disabled in the kernel. kobject_rename does not change the name on the kobject when sysfs support is not compiled in. kobject_rename without locking attempts to check the validity of a rename operation, which the kobject layer simply does not have the infrastructure to do. This patch documents the previously unstated requirement of kobject_rename that is the responsibility of the caller to provide mutual exclusion and to be certain that the new_name for the kobject is valid. This patch modifies sysfs_rename_dir in !CONFIG_SYSFS case to call kobject_set_name to actually change the kobject_name. This patch removes the bogus and misleading check in kobject_rename that attempts to see if a rename is valid. The check is bogus because we do not have the proper locking. The check is misleading because it looks like we can and do perform checking at the kobject level that we don't. Signed-off-by: Eric W. Biederman Signed-off-by: Greg Kroah-Hartman

kobject: Replace ALL occurrences of '/' with '!' instead of only the first one.

2008-08-21T17:15:34Z

A recent patch from Kay Sievers replaced the first occurrence of '/' with '!' as needed for block devices. Now do some cheap defensive coding and replace all of them to avoid future issues in this area. Signed-off-by: Ingo Oeser Cc: Kay Sievers Signed-off-by: Greg Kroah-Hartman

Example use of WARN()

Now that WARN() exists, we can fold some of the printk's into it. Signed-off-by: Arjan van de Ven Cc: Greg KH Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kobject: replace '/' with '!' in name

2008-07-22T04:54:40Z

Some (block) devices have a '/' in the name, and need special handling. Let's have that rule to the core, so we can remove it from the block class. Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman

PCI: ACPI PCI slot detection driver

2008-06-10T21:37:14Z

Detect all physical PCI slots as described by ACPI, and create entries in /sys/bus/pci/slots/. Not all physical slots are hotpluggable, and the acpiphp module does not detect them. Now we know the physical PCI geography of our system, without caring about hotplug.
