2013-12-07kobject: remove kset from sysfs immediately in kset_unregister()Bjorn Helgaas
There's no "unlink from sysfs" interface for ksets, so I think callers of kset_unregister() expect the kset to be removed from sysfs immediately, without waiting for the last reference to be released. This patch makes the sysfs removal happen immediately, so the caller may create a new kset with the same name as soon as kset_unregister() returns. Without this, every caller has to call "kobject_del(&kset->kobj)" first unless it knows it will never create a new kset with the same name. This sometimes shows up on module unload and reload, where the reload fails because it tries to create a kobject with the same name as one from the original load that still exists. CONFIG_DEBUG_KOBJECT_RELEASE=y makes this problem easier to hit. Signed-off-by: Bjorn Helgaas <> Signed-off-by: Greg Kroah-Hartman <>

2010-03-07Driver core: Constify struct sysfs_ops in struct kobj_typeEmese Revfy
Constify struct sysfs_ops. This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy <> Acked-by: David Teigland <> Acked-by: Matt Domsch <> Acked-by: Maciej Sosnowski <> Acked-by: Hans J.

2009-01-06kobject: Make Documentation/kobject.txt a little more coherent.Rusty Russell
While reading Documentation/kobject.txt: Note kobject_rename does perform any locking or have a solid notion of what names are valid so the provide must provide their own sanity checking and serialization. I expect better: You never see me hard with time word making sentence coherent stuff. Ever. Signed-off-by: Rusty Russell <> Acked-by: Eric W. Biederman <> Signed-off-by: Greg Kroah-Hartman <>
2008-10-16kobject: Fix kobject_rename and !CONFIG_SYSFSEric W. Biederman
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 <>

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!
