[GIT PULL] SCSI postmerge patches for 2.6.38 merge window

[GIT PULL] SCSI postmerge patches for 2.6.38 merge window

[James Bottomley]

This is a set of three patches I've been carrying that had a
dependencies on pieces of the block tree (which went in yesterday).
It's been rebased to go cleanly on top of current git head (and elimnate
some of the merge cruft of creating a postmerge tree).  All of the
patches have been in Linux-next for several weeks.

The two sd/sr patches are just completion of the media events
infrastructure which was in the block tree.  The main chunk is the
addition of the LIO in-kernel target infrastructure which is one of the
two competing target infrastructures which have been out of tree for
several years now.  Thanks to quite a lot of effort (particularly from
Christoph Hellwig) cleaning it up, I think it's ready for mainline
inclusion.  This piece is just the target infrastructure; we'll begin
adding the in-kernel drivers and the migration hooks for STGT (our
original user land target driver) over the next merge window.

The patch is available here:

master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-post-merge-2.6.git

The short changelog is:

Nicholas Bellinger (1):
      target: Add LIO target core v4.0.0-rc6

Tejun Heo (2):
      sd,sr: kill compat SDEV_MEDIA_CHANGE event
      sd: implement sd_check_events()

and the diffstat:

Many, many thanks to the individual kernel development community members
who have given their time and efforts for LIO v4.0 code, and for
reaching this milestone of an initial target infrastructure merge
into .38.  Without their help this would not have been possible, and
certainly not as interesting or as much fun as it has been thus far..

Many thanks to everyone who has reported bug(s) on their LIO systems,
spent the time to review individual target patches, and provide the
critical feedback throughout development of the major v3 and v4 features
features in the last 2.75 years since moving to kernel.org git.  This
list is by no means complete for all of the devels, users, vendors and
customers who have been involved up to this point, so please forgive me
if your name is not mentioned directly.  All of your hard work and
contributions are appreciated.

And a extra special thanks to Ming Zhang from the IET community for
originally recommending a ConfigFS based control plane for target mode
operation way back in August 2008.   

And finally, thanks to Marc Fleischmann, Jerome Martin, Thomas Uhl and
the entire team @ RisingTideSystems for providing commerical products
and support with the LIO target code.

Thank you!

As anyone can see in the source file drivers/target/target_core_mib.c
this patch adds a significant number of new files to procfs. I thought
that this was considered unacceptable since a long time ? Has anything
changed ?

See also http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/target/target_core_mib.c.

Nothing has changed WRT procfs, and you are correct.

But it's in now.  Submit a patch to fix this particular crapola!  :)
