Well, if the tree is ready, you shouldn't need to care ;)
That said:
I'm not going to pull linux-next, because I hate how it gets rebuilt every
time it gets done, so I would basically have to pick one at random, and
then that would be it.
I also do actually try to spread the early pulls out a _bit_, so that
if/when problems happen, there's some amount of information in the fact
that something started showing up between -git2 and -git3.
HOWEVER.
One thing that was discussed when linux-next was starting up was whether I
would maintain a next branch myself, that people could actually depend on
(unlike linux-next, which gets rebuilt).
And while I could do that for really core infrastructure changes, I really
would hate to see something like that become part of the flow - because
I'd hope things that really require it should be so rare that it's not
worth it for me to maintain a separate branch for it.
But there could be some kind of carrot here - maybe I could maintain a
"next" branch myself, not for core infrastructure, but for stuff where the
maintainer says "hey, I'm ready early, you can pull me into 'next'
already".
In other words, it wouldn't be "core infrastructure", it would simply be
stuff that you already know you'd send to me on the first day of the merge
window. And if by maintaining a "next" branch I could encourage people to
go early, _and_ let others perhaps build on it and sort out merge
conflicts (which you can't do well on linux-next, exactly because it's a
bit of a quick-sand and you cannot depend on merging the same order or
even the same base in the end), maybe me having a 'next' branch would be
worth it.
But it would have to be low-maintenance. Something I might open after
-rc4, say, and something where I'd expect people to only ask me to pull
_once_ (because they really are mostly ready, and can sort out the rest
after the merge window), and if they have no open regressions (again, the
"carrot" for good behaviour).
I'm not saying it's a great idea, but if that kind of flow makes sense to
people, maybe it should be on the table as an idea or at least see if it
might work.
But let's see how linux-next works out. Maybe all the subsystem
maintainers can just get their tree in shape, see that it merges in
linux-next, and not even need anything else. Then, when the merge window
opens, if you're ready, just let me know.
