[GIT PATCH] driver core fixes for 2.6.34-git

[GIT PATCH] driver core fixes for 2.6.34-git

[Greg KH]

Here are 3 patches for your 2.6.34-git tree.

Two documentation updates, and one fix for the sysfs attribute warning
that people have reported.

Please pull from:
	master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-core-2.6.git/

All of these patches have been in the linux-next and mm trees.

The patches will be sent as a follow-on to this message to lkml for
people to see.

thanks,

greg k-h

[PATCH 1/3] Documentation: -stable rules: upstream commit ID requirement reworded

[Greg Kroah-Hartman]

From: Stefan Richter <stefanr@s5r6.in-berlin.de>

It is a hard requirement to include the upstream commit ID in the
changelog of a -stable submission, not just a courtesy to the stable
team.  This concerns only mail submission though, which is no longer
the only way into stable.  (Also, fix a double "the".)

I find the upstream commit ID to be highly useful when looking at
commits in the stable tree.  So it would be nice IMHO if we could
enforce this requirement regardless of whether the submission path is
via e-mail or git.

In the semi-automatic submission path via git --- i.e. of commits which
feature a Cc: stable@kernel.org line in the changelog when they show up
in Linus' tree --- the upstream commit ID is not known to the submitter
at the time of submission.  Apparently Greg's scripts modify the
changelogs respectively when he cherry-picks from linux-2.6.git, so the
requirement is also always fulfilled with this alternative submission path.

E.g. as in http://lkml.org/lkml/2010/4/22/294 which was apparently
submitted the semi-automatic way, via
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=44fef22416886a04d432043f741a6faf2c6ffefd

Or do you mean submission directly from a developer's git tree to stable
via git pull by Greg?  Is this been done?  If yes, I suppose this comes
only from people who know very well how a stable patch is meant to look
like.  Nevertheless I could send another adjustment for
Documentation/stable_kernel_rules.txt if this is another actual
submission path.

No, it's not a real submission patch, and yes, I always require a git
commit id in the patch.  If I don't have it, it is explained in the
patch why it is not in Linus's tree.

Don't worry, I think the current wording is fine.

thanks,

Thanks for clarifying, I didn't realize the wording was referring to the cc: stable@ path, where the stable team adds the commit id reference themselves once it's available.

[GIT PATCH] driver core fixes for 2.6.34-git

[Greg KH]

Here are a number of bugfixes for the driver core for your 2.6.34-git
tree.

This series should resolve all of the sysfs lockdep warnings that have
been reported numerous times.  It also includes a number of
documentation updates and other small fixes.

Please pull from:
	master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-core-2.6.git/

All of these patches have been in the linux-next and mm trees.

The patches will be sent as a follow-on to this message to lkml for
people to see.

thanks,
