* sysdev: detect multiple driver registrationsBen Dooks2008-04-19
| | | | | | | | | | | | | | | | I've just found how easy it is to accidentally register a sysdev_driver for two different classes. When this happens, bad things happen as the sysdev_driver structure keeps has the list entry for the driver registration. The following patch makes a WARN_ON() if this happens, although I think BUG_ON or returning -EAGAIN could also be valid responses to this.

* sysdev: fix problem with sysdev_class being re-registeredGreg Kroah-Hartman2008-03-10
| | | | | | | | | | | | | | | | We need to initialize the kobject for a sysdev_class as it could have been recycled (stupid static kobjects...) We also do the same thing in case sysdev devices are being re-registered. Thanks to Balaji Rao <balajirrao@gmail.com> for pointing out the problem.

* Driver core: change sysdev classes to use dynamic kobject namesKay Sievers2008-01-24
| | | | | | | | | | All kobjects require a dynamically allocated name now. We no longer need to keep track if the name is statically assigned, we can just unconditionally free() all kobject names on cleanup.

* Kobject: convert drivers/* from kobject_unregister() to kobject_put()Greg Kroah-Hartman2008-01-24
| | | | | | | | | | | There is no need for kobject_unregister() anymore, thanks to Kay's kobject cleanup changes, so replace all instances of it with kobject_put(). Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Kobject: change drivers/base/sys.c to use kobject_init_and_addGreg Kroah-Hartman2008-01-24
| | | | | | | | | Stop using kobject_register, as this way we can control the sending of the uevent properly, after everything is properly initialized. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* kset: convert /sys/devices to use kset_createGreg Kroah-Hartman2008-01-24
| | | | | | | | | | Dynamically create the kset instead of declaring it statically. We also rename devices_subsys to devices_kset to catch all users of the variable. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* kobject: remove struct kobj_type from struct ksetGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | | | | 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.

* sysdev: remove global sysdev drivers listAkinobu Mita2007-10-12
| | | | | | | | | | | | | | | | | | | No one uses sysdev_drivers. Because no one calls sysdev_driver_register with NULL class. And it is difficult to imagine that someone want to implement a global sysdev driver which is called with all sys_device on any kind of sysdev_class. So this patch removes global sysdev_drivers list and update comments for this change.

* remove "struct subsystem" as it is no longer neededGreg Kroah-Hartman2007-05-02
| | | | | | | | | | | We need to work on cleaning up the relationship between kobjects, ksets and ktypes. The removal of 'struct subsystem' is the first step of this, especially as it is not really needed at all. Thanks to Kay for fixing the bugs in this patch.

* [PATCH] fix missing includesTim Schmielau2005-10-30
| | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

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!
