You're suggesting that I should develop my patches on top of what I
speculate that Andrew will eventually merge in -mm? I don't have that

Unless your fixes, which seem to still be under development considering
your discussion with KOSAKI in those threads, are going into 2.6.35 during
the rc cycle, then there's no difference in them being merged as part of
this patchset since they are duplicated here. So you'll need to convince
Andrew they are rc material otherwise it doesn't matter.
