Every time I come up with a complaint about ocfs2, the Oracle guys 
manage to shoot me down.  I think it's OK to merge.

seems sane, though there are some whitespace niggles that should be 
cleaned up

send through netdev, as is proper

I hate to say it, since its my own employer, but I agree:  wait for 
in-kernel users, at the very least.

I don't like connector

We should ask hpa what he needs for kernel.org.  Ideally kernel.org 
probably wants <something> that facilitates listening to <something> for 
a list of files being changed.  That would greatly speed up the robots, 
and possibly rsync-like activities too.

Testing?  The goal behind the patch is certainly good, but I worry about 
exposure.

If I could vote more than once, I would!  I really like cachefs, and 
have been pushing for its inclusion for a while.

I'm not particularly pleased with these, and indeed vendors ARE shipping 
other crashdump methods.

The plugin stuff is crap.  This is not a filesystem but a filesystem + 
new layer.  IMO considered in that light, it duplicates functionality 
elsewhere.

agreed (though I think 9P is neat)

"It has been said" -- its true.  A userspace NFS server can do 100% of 
userspace FS functionality.
