Linus,
Here are all of the ocfs2 changes without the reflink(2)
system call. The snapshot functionality is still available via the
ocfs2 ioctl(2). I'm going to formulate up a new system call based on
the discussion we've had, but clearly that's not something for 2.6.32
anymore.
Please pull.
The following changes since commit 8379e7c46cc48f51197dd663fc6676f47f2a1e71:

"But then she looks me in the eye
And says, 'We're going to last forever,'
And man you know I can't begin to doubt it.
Cause it just feels so good and so free and so right,
I know we ain't never going to change our minds about it, Hey!
Here comes my girl."
