In this case, current pci_hotplug core will call kobject_init_and_add() muliple time with the same name. This is the cause of this problem. To fix this problem, this patch adds the check into pci_hp_register() to see if the slot with the same name.

* driver core: add way to get to bus ksetGreg Kroah-Hartman2008-01-251-1/+4
| | | | | | | | | | This allows an easier way to get to the kset associated with a struct bus_type (you have three to choose from...)

* kobject: remove struct kobj_type from struct ksetGreg Kroah-Hartman2008-01-251-3/+4
| | | | | | | | | | | | | | | | | We don't need a "default" ktype for a kset. We should set this explicitly every time for each kset. This change is needed so that we can make ksets dynamic, and cleans up one of the odd, undocumented assumption that the kset/kobject/ktype model has. This patch is based on a lot of help from Kay Sievers.

* sysfs: kill sysfs_update_file()Tejun Heo2007-10-121-60/+0Star
| | | | | | | | | | | | | | sysfs_update_file() depends on inode->i_mtime but sysfs iondes are now reclaimable making the reported modification time unreliable. There's only one user (pci hotplug) of this notification mechanism and it reportedly isn't utilized from userland. Kill sysfs_update_file().

* remove "struct subsystem" as it is no longer neededGreg Kroah-Hartman2007-05-031-2/+2
| | | | | | | | | | | We need to work on cleaning up the relationship between kobjects, ksets and ktypes.

* Linux-2.6.12-rc2Linus Torvalds2005-04-171-0/+715
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
