It's best to split things up per subsystem in > that case. I asked for this. I'll merge everything, spend a few weeks gathering up maintainer acks. Anything which a subsystem maintainer merges will be reported by Stephen and I'll drop that particular patch. This way, nothing gets lost. I take this approach often and it works. If these were sent as a bunch of individual patches then it would be up to the sender to keep track of what has been merged and what hasn't. That person will be resending some stragglers many times. Until they give up and some patches get permanently lost. Scale all that across many senders and the whole process becomes costly and unreliable. Whereas centralizing it on akpm is more efficient, more reliable, more scalable, lower latency and less frustrating for senders.
