kobject.h: fix build when CONFIG_HOTPLUG is disabled

2011-02-18T16:02:10+00:00

When CONFIG_HOTPLUG is not enabled, the inline function add_uevent_var()
needs to have its __attribute__ before the function name/parameters,
otherwise there are syntax errors.

kobject: Add missing format attribute specifications

2011-02-03T23:10:18+00:00

Several functions in  accept printf-style arguments.
Some of these functions have been annotated with a format attribute
declaration while others have not been annotated. Add a format attribute
specification where it is missing.

kobject: Introduce kset_find_obj_hinted.

2010-10-22T17:16:44+00:00

One call chain getting to kset_find_obj is:
  link_mem_sections()
    find_mem_section()
      kset_find_obj()

This is done during boot.  The memory sections were added in a linearly
increasing order and link_mem_sections tends to utilize them in that
same linear order.

Introduce a kset_find_obj_hinted which is passed the result of the
previous kset_find_obj which it uses for a quick "is the next object
our desired object" check before falling back to the old behavior.

kobject: Break the kobject namespace defs into their own header

2010-08-24T01:12:46+00:00

Break the kobject namespace defs into their own header to avoid a header file
inclusion ordering problem between linux/sysfs.h and linux/kobject.h.

This fixes the build breakage on older versions of gcc.

netns: Teach network device kobjects which namespace they are in.

2010-05-21T16:37:32+00:00

The problem.  Network devices show up in sysfs and with the network
namespace active multiple devices with the same name can show up in
the same directory, ouch!

To avoid that problem and allow existing applications in network namespaces
to see the same interface that is currently presented in sysfs, this
patch enables the tagging directory support in sysfs.

By using the network namespace pointers as tags to separate out the
the sysfs directory entries we ensure that we don't have conflicts
in the directories and applications only see a limited set of
the network devices.

sysfs: Comment sysfs directory tagging logic

2010-05-21T16:37:31+00:00

Add some in-line comments to explain the new infrastructure, which
was introduced to support sysfs directory tagging with namespaces.
I think an overall description someplace might be good too, but it
didn't really seem to fit into Documentation/filesystems/sysfs.txt,
which appears more geared toward users, rather than maintainers, of
sysfs.

(Tejun, please let me know if I can make anything clearer or failed
altogether to comment something that should be commented.)

kobj: Add basic infrastructure for dealing with namespaces.

2010-05-21T16:37:31+00:00

Move complete knowledge of namespaces into the kobject layer
so we can use that information when reporting kobjects to
userspace.

Driver core: Constify struct sysfs_ops in struct kobj_type

2010-03-08T01:04:49+00:00

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
