Why bypass -mm tree ?

I think you planned to merge this via -mm tree and, then, posted patches
to linux-mm with CC -mm guys.

I think you posted 2011/09/16 at the last time, v10. But no further submission
to gather acks/reviews from Mel, Johannes, Andrew, Hugh etc.. and no inclusion
request to -mm or -next. _AND_, IIUC, at v10, the number of posted pathces was 6.
Why now 8 ? Just because it's simple changes ?

I don't have heavy concerns to the codes itself but this process as bypassing -mm
or linux-next seems ugly.

Thanks,
