* Kobject: auto-cleanup on final unrefKay Sievers2008-01-24
| | | | | | | | | | | | | | | | We save the current state in the object itself, so we can do proper cleanup when the last reference is dropped. If the initial reference is dropped, the object will be removed from sysfs if needed, if an "add" event was sent, "remove" will be send, and the allocated resources are released. This allows us to clean up some driver core usage as well as allowing us to do other such changes to the rest of the kernel.

* Driver core: convert block from raw kobjects to core devicesKay Sievers2008-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | This moves the block devices to /sys/class/block. It will create a flat list of all block devices, with the disks and partitions in one directory. For compatibility /sys/block is created and contains symlinks to the disks. /sys/class/block |-- sda -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda |-- sda1 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda1 |-- sda10 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda10 |-- sda5 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda5 |-- sda6 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda6 |-- sda7 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda7 |-- sda8 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda8 |-- sda9 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda9 `-- sr0 -> ../../devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0/block/sr0 /sys/block/ |-- sda -> ../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda `-- sr0 -> ../devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0/block/sr0 Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Driver core: fix class glue dir cleanup logicKay Sievers2008-01-24
| | | | | | | | | | | | We should remove the glue directory between the class and the bus device _after_ we sent out the 'remove' event for the device, otherwise the parent relationship is no longer valid, and composing the path with deleted sysfs entries will not work.

* Driver core: fix race in __device_release_driverAlan Stern2008-01-24
| | | | | | | | | | | | | | | | | | This patch (as1013) was suggested by David Woodhouse; it fixes a race in the driver core. If a device is unregistered at the same time as its driver is unloaded, the driver's code pages may be unmapped while the remove method is still running. The calls to get_driver() and put_driver() were intended to prevent this, but they don't work if the driver's module count has already dropped to 0. Instead, the patch keeps the device on the driver's list until after the remove method has returned. This forces the necessary synchronization to occur.

* Driver core: clean up debugging messagesGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | | | The driver core debugging messages are a mess. This provides a unified message that makes them actually useful. The format for new kobject debug messages should be: driver/bus/class: 'OBJECT_NAME': FUNCTION_NAME: message.\n Note, the class code is not changed in this patch due to pending patches in my queue that this would conflict with. A later patch will clean them up. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Driver core: move the static kobject out of struct driverGreg Kroah-Hartman2008-01-24
| | | | | | | | | | This patch removes the kobject, and a few other driver-core-only fields out of struct driver and into the driver core only.

* Driver core: move the driver specific module code into the driver coreGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | | The module driver specific code should belong in the driver core, not in the kernel/ directory. So move this code. This is done in preparation for some struct device_driver rework that should be confined to the driver core code only. This also lets us keep from exporting these functions, as no external code should ever be calling it. Thanks to Andrew Morton for the !CONFIG_MODULES fix.

* driver core: remove fields from struct bus_typeGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | | struct bus_type is static everywhere in the kernel. This moves the kobject in the structure out of it, and a bunch of other private only to the driver core fields are now moved to a private structure.

This will make it easier to move these fields to be dynamic in a future patch. The only user of this is the PCI core which horribly abuses this interface to rearrange the order of the pci devices.
