Fengguang,
it looks like the kernel build robot _only_ tests the actual rc
kernels, and doesn't bisect down where the error started.
Any change that when it notices an error, it would bisect it, like it
does for linux-next?

Hi Linus,

Nah, that's an illusion. :)
It's a per-branch summary report _in addition to_ per-bisect reports.
The former shows all active (not-yet-fixed) error/warnings in the
current branch HEAD; the latter shows result of one bisect.
Typically for all error messages showed in this summary report, there
have been individual bisect reports sent out to the relevant authors
and committers. I'll give concrete examples in the bottom.
>Any change that when it notices an error, it would bisect it, like it

It should already be so -- otherwise it's a bug in 0day robot. In fact
your tree _implicitly_ receives much more tests than linux-next, and
linux-next receives more tests than other individual developer trees.
It works like this:
The robot will normally test all pushed branch HEADs of all git trees.
IOW, each of your (and others') git push will trigger tests -- unless
when occasionally the robot cannot catch up.
The RC kernels will effectively receive _much more_ tests, since
developers typically base their git branches on RC releases. So
whenever they do git push, the triggered tests on their branch HEAD
will automatically cover its base RC kernel.
Whenever an error is found in a commit (typically the branch HEAD),
the robot will traverse backwards in its git history and test these
critical points until a GOOD point is found for starting the bisect:
- the branch's BASE commit (typically an RC kernel)
- the official releases (eg. 4.14 => 4.13 => 4.12 => ...)
We'll give up when the bug is found to exist in too old kernel, since
old bugs are likely either uninteresting (no one cares to fix) or hard
to bisect.

hi Linus, the robot will also bisect down the error if issue is found
on linus repo.
The regression below is reported at below mail, with a reminder to author
