Yes, like I did in my previous patchset.

I can easily imagine how you progress the work, because I have some 
topic branch in my local repository as well, for PCM core. They're also 
ready, like yours. However, I accept changes of HEAD of remote branch. 
HEAD tends to move regardless of my work. When posting my patchset, I 
always work to rebase to the HEAD. This often brings me a bit work, and 
next week I'll surely do it, but it's natural to me.

Here, I don't necessarily request you to merge them promptly. I'm just 
interested in your current situation, in short, the reason to postpone 
this patch. In my eyes, this patch surely brings conflict to your future 
patchset, but it has a small changes and the occurred conflict can be 
fixed quickly. I understand that you'd like to save the time for it.

Hm.

It depends on the shape of patchset, regardless of the importance, in my 
humble opinion.

When it includes large changes, it takes longer time to review. When a 
patchset is splitted into small parts and posted sequentially with each 
of topics, reviewer finishes his or her work within shorter time 
relatively. I'll post my comments to your recent work later, but here 
your patchset looks to include refactoring, integration and more. It 
seems takes more time to merge into HEAD and I cannot post the series of 
my works (they depends each other) even if my patches are enough small. 
That's my concern here.
