Are you sure they don't depend on the previous patches ? We're already
having fallover from the SCSI tree merging some of them while I haven't
merge the previous ones yet...

Geert, there are several "procedural" issues with your series here: In
addition to the whole thing being submitted too late that is :-)

You don't have the same CC list on all patches. That is fine except that
you also don't provide merge instructions after the signature, such as
"this patch depends on XX from this series" etc...

A bunch of them do have such dependencies. In fact, there's even a patch
that changes something in the block layer (it's not a big deal, just
adding an accessor, but I still -need- an Ack from Jens to merge it) and
so I have to block all patches that depend on this one. But then, we
have indirect dependencies where some patch don't apply because they
touch the same file that was patched by the patch who had the dependency
etc...

I ended up stopping mid-way through the series. I'll push some of the
patches to my -next branch tonight, and the rest once I get the Ack from
Jens.

I recommend all maintainers (scsi, alsa) just drop these patches for now
and instead give me Ack's so I can merge them via the powerpc tree along
with their respective dependencies. James, feel free to do a revert if
you don't want to rebase, that will break bisect on ps3 for a little
while, but that's the price Geert will have to pay for his mistakes :-)

Cheers,
Ben.
