- uses a kset in "struct class" to keep track of all directories belonging to this class - merges with the /sys/devices/virtual logic. - removes the namespace-dir if the last member of that class leaves the directory. There may be locking or refcounting fixes left, I stopped when it seemed to work with network and sound modules. :) From: Kay Sievers <kay.sievers@vrfy.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.

This moves the device symlink back to sysfs even if CONFIG_SYSFS_DEPRECATED is enabled as too many userspace programs (well, HAL), still rely on this link to be present. I will rework the ability for sysfs to change layouts like this in the future, but for now, this patch should fix people's network connections.

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>

This defines a new platform_driver_probe() method allowing the driver's probe() method, and its support code+data, to safely live in __init sections for typical system configurations. Many system-on-chip processors could benefit from this API, to the tune of recovering hundreds to thousands of bytes per driver. That's memory which is currently wasted holding code which can never be called after system startup, yet can not be removed. It can't be removed because of the linkage requirement that pointers to init section code (like, ideally, probe support) must not live in other sections (like driver method tables) after those pointers would be invalid.
