sysfs: make kobj point to sysfs_dirent instead of dentry

2007-07-11T23:09:08+00:00

As kobj sysfs dentries and inodes are gonna be made reclaimable,
dentry can't be used as naming token for sysfs file/directory, replace
kobj->dentry with kobj->sd.  The only external interface change is
shadow directory handling.  All other changes are contained in kobj
and sysfs.

Driver core: add missing kset uevent

2007-07-11T23:09:01+00:00

We get uevents for a bus/class going away, but not one registering.
Add the missing uevent in kset_register(), which will send an
event for a new bus/class. Suppress all unwanted uevents for bus
subdirectories like /bus/*/devices/, /bus/*/drivers/.

Now we get for module usbcore:
  add      /module/usbcore (module)
  add      /bus/usb (bus)
  add      /class/usb_host (class)
  add      /bus/usb/drivers/hub (drivers)
  add      /bus/usb/drivers/usb (drivers)
  remove   /bus/usb/drivers/usb (drivers)
  remove   /bus/usb/drivers/hub (drivers)
  remove   /class/usb_host (class)
  remove   /bus/usb (bus)
  remove   /module/usbcore (module)

instead of:
  add      /module/usbcore (module)
  add      /bus/usb/drivers/hub (drivers)
  add      /bus/usb/drivers/usb (drivers)
  remove   /bus/usb/drivers/usb (drivers)
  remove   /bus/usb/drivers/hub (drivers)
  remove   /class/usb_host (class)
  remove   /bus/usb/drivers (bus)
  remove   /bus/usb/devices (bus)
  remove   /bus/usb (bus)
  remove   /module/usbcore (module)

remove "struct subsystem" as it is no longer needed

2007-05-03T01:57:59+00:00

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.

This dots some i's and crosses some t's after left over from when
kobject_kset_add_dir was built from kobject_add_dir.

kobject core: remove rwsem from struct subsystem

2007-04-27T17:57:31+00:00

It isn't used at all by the driver core anymore, and the few usages of
it within the kernel have now all been fixed as most of them were using
it incorrectly.  So remove it.

Now the whole struct subsys can be removed from the system, but that's
for a later patch...

driver core: fix namespace issue with devices assigned to classes

2007-04-27T17:57:28+00:00

  - 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. :)
