Revert "Driver core: remove class_device_*_bin_file"

2007-10-31T19:51:29Z

This reverts commit fcd239d3d5575e5cc63aab5c33cf6dc66904f6d6. I messed up, ia64 still uses these files in the current tree, and now can not build the pci code, which all ia64 boxes seem to require :) This fixes that mistake. Signed-off-by: Greg Kroah-Hartman

Driver core: remove class_device_*_bin_file

2007-10-31T04:52:33Z

These functions are not used by anyone, so remove them from the tree. The class_device code will be removed soon anyway, so no future users will ever be possible. Signed-off-by: Greg Kroah-Hartman

Driver core: rename ktype_class

2007-10-12T21:51:11Z

This makes it a bit more sane when trying to figure out how to clean up the ktype mess. Based on a larger patch from Kay Sievers Cc: Kay Sievers Signed-off-by: Greg Kroah-Hartman

driver core: remove subsystem_init()

2007-10-12T21:51:11Z

There is only one user of it, and it is only a wrapper for kset_init(). Signed-off-by: Greg Kroah-Hartman

Driver core: remove subsys_get()

2007-10-12T21:51:01Z

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. Signed-off-by: Greg Kroah-Hartman

Driver core: remove subsys_put()

2007-10-12T21:51:01Z

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. Signed-off-by: Greg Kroah-Hartman

Driver core: remove subsys_set_kset

2007-10-12T21:51:01Z

This macro is only used by the driver core and is held over from when we had subsystems. It is not needed anymore. Signed-off-by: Greg Kroah-Hartman

Driver core: change add_uevent_var to use a struct

2007-10-12T21:51:01Z

This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

driver-core: make devt_attr and uevent_attr static

2007-07-11T23:09:06Z

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: Tejun Heo Signed-off-by: Greg Kroah-Hartman

sysfs: kill unnecessary attribute->owner

2007-07-11T23:09:06Z

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.)
