I'll post a more detailed and general update in a few days when I'm back 
in Sydney, but briefly, send me a pull request against my next-general 
branch, which replaces the 'next' branch.  I'll sync that to -rc2 after 
this email.

I'll fetch your branch into my next-smack branch, which will track 

All of these subsystem branches and next-general will be merged into 
next-testing, for use by Stephen Rothwell for linux-next, and any other 
general testing which may be done.

When the merge window opens, I'll merge the subsystem branches into 
next-for-linus for him to pull.  If all is going well, this will be the 
same as next-testing.  If there are problems in any of the branches, they 
can be left out of next-for-linus until they're resolved.

Linus can then pull from that to get everything at once, or pull individual 
branches as he sees fit.

In summary: track my next-general branch instead of 'next', and your 
workflow is otherwise unchanged.

How does that sound?
