Perhaps being less accepting of patches during merge window is one aspect, as the merge window leading up to this cycle was almost the same review load as when the cycle started.
I'm having trouble understanding what you said here?
Sorry, what I mean to say is that in mm we're pretty open to taking stuff in the merge window, esp. now we have mm-new.
And last merge window my review load felt similar to during a cycle, which was kind of crazy.
So I wonder if we should be less accommodating and simply say 'sorry it's the merge window, no submissions accepted'?
hm, I always have a lot of emails piled up by the time mm-stable gets merged upstream. That ~1 week between "we merged" and "-rc1" is a nice time to go through that material and add it to mm-new. I think it smooths things out. I mean, this is peak time for people to be considering the new material?
I'm confused, why is the merge window a good time to consider new material?
People have the entirety of the cycle to submit new material, and they do so.
And equally, people are sending new revisions of old code, engaging in discussion from old series etc. during the merge window also.
What happens is you essentially have reviewers work 9 weeks instead of 7 for a cycle without much of a let up (+ so no break from it), based on workload from the past cycle/merge window.
I mean I can only ask that perhaps we consider not doing this in mm (I gather many other subsystems equally have a kinda 'freeze' during this time).
(ot, that backlog is always >400 emails and a lot of that gets tossed out anyway - either it's just too old so I request a refresh or there was a new version, or review was unpromising, etc).
Right, which actually makes everything a lot more uncertain from a reviewer's point of view, as we don't definitely have a solid git base, mm-new isn't synced with Linus's tree very much during this time etc.
Which makes the merge window actually even worse for this stuff.
From the point of view of avoiding burn out, it'd be good to manage expectations a bit on this.
Personally I remember literally saying to David during the last merge window 'well I hoped I could go off and work on my own stuff instead of just review, guess not then' :)
THP is a particularly busy area at the moment which is part of all this.
