That patch was accepted as it fixed a oops.  It also went in for
2.6.16-rc2, which is much earlier than 2.6.16-rc4, and it had been in
the -mm tree for quite a while for people to test it out and verify that
it didn't break anything.  I didn't hear any complaints about it, so
that is why it went in.

In contrast, this patch series creates a new api and doesn't necessarily
fix any reported bugs.  It also has not had the time to be tested in the
-mm tree, and there is quite a lot of disagreement about the patches on
the lists.  All of that combinded makes it not acceptable for so late in
the -rc cycle (remember, -rc4 means only serious bug fixes.)

Care to resend the series based on all of the comments you have
addressed so far?  I'll be glad to review it then.
