driver core: Introduce device_move(): move a device to a new parent.

2006-12-01T22:52:01+00:00

Provide a function device_move() to move a device to a new parent device. Add
auxilliary functions kobject_move() and sysfs_move_dir().
kobject_move() generates a new uevent of type KOBJ_MOVE, containing the
previous path (DEVPATH_OLD) in addition to the usual values. For this, a new
interface kobject_uevent_env() is created that allows to add further
environmental data to the uevent at the kobject layer.

[PATCH] kobject: quiet errors in kobject_add

2006-05-21T19:59:21+00:00

People don't like released kernels yelling at them, no matter how real the
error might be.  So only report it if CONFIG_KOBJECT_DEBUG is enabled.

Sent on request of Andrew Morton.

(akpm: should bring this back post-2.6.17)

[PATCH] sysfs: Allow sysfs attribute files to be pollable

2006-04-14T18:41:24+00:00

It works like this:
  Open the file
  Read all the contents.
  Call poll requesting POLLERR or POLLPRI (so select/exceptfds works)
  When poll returns,
     close the file and go to top of loop.
   or lseek to start of file and go back to the 'read'.

Events are signaled by an object manager calling
   sysfs_notify(kobj, dir, attr);

If the dir is non-NULL, it is used to find a subdirectory which
contains the attribute (presumably created by sysfs_create_group).

This has a cost of one int  per attribute, one wait_queuehead per kobject,
one int per open file.

The name "sysfs_notify" may be confused with the inotify
functionality.  Maybe it would be nice to support inotify for sysfs
attributes as well?

This patch also uses sysfs_notify to allow /sys/block/md*/md/sync_action
to be pollable

[PATCH] Kobject: provide better warning messages when people do stupid things

2006-03-20T21:42:59+00:00

Now that kobject_add() is used more than kobject_register() the kernel
wasn't always letting people know that they were doing something wrong.
This change fixes this.
