kobject: update the copyrights

2007-10-12T21:51:12+00:00

I've been hacking on these files for a while now, might as well make it
official...

driver core: remove subsystem_init()

2007-10-12T21:51:11+00:00

There is only one user of it, and it is only a wrapper for kset_init().

sysfs: move sysfs file poll implementation to sysfs_open_dirent

2007-10-12T21:51:11+00:00

Sysfs file poll implementation is scattered over sysfs and kobject.
Event numbering is done in sysfs_dirent but wait itself is done on
kobject.  This not only unecessarily bloats both kobject and
sysfs_dirent but is also buggy - if a sysfs_dirent is removed while
there still are pollers, the associaton betwen the kobject and
sysfs_dirent breaks and kobject may be freed with the pollers still
sleeping on it.

This patch moves whole poll implementation into sysfs_open_dirent.
Each time a sysfs_open_dirent is created, event number restarts from 1
and pollers sleep on sysfs_open_dirent.  As event sequence number is
meaningless without any open file and pollers should have open file
and thus sysfs_open_dirent, this ephemeral event counting works and is
a saner implementation.

This patch fixes the dnagling sleepers bug and reduces the sizes of
kobject and sysfs_dirent by one pointer.

Driver core: exclude kobject_uevent.c for !CONFIG_HOTPLUG

2007-10-12T21:51:06+00:00

Move uevent specific logic from the core into kobject_uevent.c, which
does no longer require to link the unused string array if hotplug
is not compiled in.

sysfs: Remove first pass at shadow directory support

2007-10-12T21:51:03+00:00

While shadow directories appear to be a good idea, the current scheme
of controlling their creation and destruction outside of sysfs appears
to be a locking and maintenance nightmare in the face of sysfs
directories dynamically coming and going.  Which can now occur for
directories containing network devices when CONFIG_SYSFS_DEPRECATED is
not set.

This patch removes everything from the initial shadow directory support
that allowed the shadow directory creation to be controlled at a higher
level.  So except for a few bits of sysfs_rename_dir everything from
commit b592fcfe7f06c15ec11774b5be7ce0de3aa86e73 is now gone.

kobject: remove the static array for the name

2007-10-12T21:51:02+00:00

Due to historical reasons, struct kobject contained a static array for
the name, and a dynamic pointer in case the name got bigger than the
array.  That's just dumb, as people didn't always know which variable to
reference, even with the accessor for the kobject name.

This patch removes the static array, potentially saving a lot of memory
as the majority of kobjects do not have a very long name.

Thanks to Kay for the idea to do this.

Driver core: remove subsys_get()

2007-10-12T21:51:01+00:00

There are no more subsystems, it's a kset now so remove the function and
the only two users, which are in the driver core.

Driver core: remove kset_set_kset_s

2007-10-12T21:51:01+00:00

This macro is only used by the driver core and is held over from when we
had subsystems.  It is not needed anymore.
