devt_attr and uevent_attr are either allocated dynamically with or embedded in device and class_device as they needed their owner field set to the module implementing the driver. Now that sysfs implements immediate disconnect and owner field removed from struct attribute, there is no reason to do this. Remove these attributes from [class_]device and use static attribute structures instead. Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

As the new-style class devices (as opposed to old-style struct class_device) are becoming more widely used, I noticed that the dev_printk-based functions are not working properly with these. New-style class devices have no driver nor bus, almost by definition, and as a result dev_driver_string(), which is used as the first parameter of dev_printk, resolves to an empty string. This causes entries like the following to show in my logs: i2c-2: adapter [SMBus stub driver] registered Notice the unaesthetical leading whitespace. In order to fix this problem, I suggest that we extend dev_driver_string to deal with new-style class devices: Signed-off-by: NJean Delvare <khali@linux-fr.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

Revert all this. It can cause device-mapper to receive a different major from earlier kernels and it turns out that the Amanda backup program (via GNU tar, apparently) checks major numbers on files when performing incremental backups. Which is a bit broken of Amanda (or tar), but this feature isn't important enough to justify the churn.

This patch (as868) adds a helper routine for device drivers that need to set up a callback to perform some action in a different process's context. This is intended for use by attribute methods that want to unregister themselves or their parent device. Attribute method calls are mutually exclusive with unregistration, so such actions cannot be taken directly. Two attribute methods are converted to use the new helper routine: one for SCSI device deletion and one for System/390 ccwgroup devices.

Implement device resource management, in short, devres. A device driver can allocate arbirary size of devres data which is associated with a release function. On driver detach, release function is invoked on the devres data, then, devres data is freed. devreses are typed by associated release functions. Some devreses are better represented by single instance of the type while others need multiple instances sharing the same release function. Both usages are supported. devreses can be grouped using devres group such that a device driver can easily release acquired resources halfway through initialization or selectively release resources (e.g. resources for port 1 out of 4 ports). This patch adds devres core including documentation and the following managed interfaces. * alloc/free : devm_kzalloc(), devm_kzfree() * IO region : devm_request_region(), devm_release_region() * IRQ : devm_request_irq(), devm_free_irq() * DMA : dmam_alloc_coherent(), dmam_free_coherent(), dmam_declare_coherent_memory(), dmam_pool_create(), dmam_pool_destroy() * PCI : pcim_enable_device(), pcim_pin_device(), pci_is_managed() * iomap : devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(), devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(), pcim_iomap(), pcim_iounmap() Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

This allows us to add type specific attributes, uevent vars and release funtions. A subsystem can carry different types of devices like the "block" subsys has disks and partitions. Both types create a different set of attributes, but belong to the same subsystem. This corresponds to the low level objects: kobject -> device (object/device data) kobj_type -> device_type (type of object/device we are embedded in) kset -> class/bus (list of objects/devices of a subsystem) Signed-off-by: NKay Sievers <kay.sievers@novell.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

If we allow NULL as the new parent in device_move(), we need to make sure that the device is placed into the same place as it would if it was newly registered: - Consider the device virtual tree. In order to be able to reuse code, setup_parent() has been tweaked a bit. - kobject_move() can fall back to the kset's kobject. - sysfs_move_dir() uses the sysfs root dir as fallback.

For node-aware skb allocations we need information about the node in struct net_device or struct device. Davem suggested to put it into struct device which this patch does. In particular: - struct device gets a new int numa_node member if CONFIG_NUMA is set - there are two new helpers, dev_to_node and set_dev_node to transparently deal with the non-numa case - for pci devices the node-info is set to the value we get from pcibus_to_node. Note that for some architectures pcibus_to_node doesn't work yet at the time we call it currently. This is harmless and will just mean skb allocations aren't node-local on this architectures until the implementation of pcibus_to_node on these architectures have been updated (There are patches for x86 and x86_64 floating around) [akpm@osdl.org: cleanup] Signed-off-by: NChristoph Hellwig <hch@lst.de> Cc: Christoph Lameter <clameter@engr.sgi.com> Cc: Greg KH <greg@kroah.com> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>
