ae57a85642 [PATCH] kobject: quiet errors in kobject_add
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)

4508a7a734 [PATCH] sysfs: Allow sysfs attribute files to be pollable
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

dcd0da0021 [PATCH] Kobject: provide better warning messages when people do stupid things
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.

b365b3daf2 [PATCH] kobject: don't oops on null kobject.name
kobject_get_path() will oops if one of the component names is
NULL.  Fix that by returning NULL instead of oopsing.

c171fef5c8 [PATCH] kobject_add() must have a valid name in order to succeed.
So we might as well check to verify this, and let the user know that
something is wrong if they didn't do it correctly, instead of oopsing
later on in kobject_get_name() or somewhere else.

312c004d36 [PATCH] driver core: replace "hotplug" by "uevent"
Leave the overloaded "hotplug" word to susbsystems which are handling
real devices. The driver core does not "plug" anything, it just exports
the state to userspace and generates events.

4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
