This caught my eye due to my earlier report:

Are you sure these configurations built sucessfully?

Author: Ingo Molnar <mingo@kernel.org>
Date: Mon Mar 21 11:05:50 2022 +0100
headers/prep: Fix header to build standalone: <linux/psi.h>
Add the <linux/cgroup-defs.h> dependency to <linux/psi.h>, because
cgroup_move_task() will dereference 'struct css_set'.
( Only older toolchains are affected, due to variations in
the implementation of rcu_assign_pointer() et al. )

I am curious to know how this error was not caught by these builds?
Perhaps an old .config from a previous allmodconfig is being reused,
rather than just running "make allmodconfig"? If that is the case, it
seems like that methodology will miss out on new configuration options
over time.
Cheers,
Nathan

Hi Nathan,
Thanks for your reminding, the problem commit is 4ff8f2ca6ccd
("sched/headers: Reorganize, clean up and optimize kernel/sched/sched.h
dependencies"),
the bot has sent two build reports related to it:

Oh *PLEASE* never report a branch as building if there's errors.
It could be I (force) push a branch multiple times before I get any
0day reports back (0day has gotten *soooo* slow) so I only ever look at
the latest report -- possibly days later.
If you then falsly report the branch as being good, because you're
suppressing errors, things *will* go bad.

Hi Peter,
Sorry for the bad experience, I'm not sure the meaning of "a branch as
building", is there a way to know the branch is not ready, or we can
postpone the test for a branch by a day?

yes, current the summary report only shows the errors that bisected
successfully in a cycle, but it may causes some errors missing
and old errors still in the report, we plan to redesign the report
to present all (may a lot) recent errors.

I was just commenting in general; never send a mail with "SUCCESS" in
the subject (as per this thread) when there are errors/warns with it,
supressed or otherwise.
If you do want to supress warnings (I'm not sure why; a few more emails
in my inbox really aren't going to make a difference) then please state
so explicitly with a link to the email with the report.
The thing I worry about is that I often wait for a SUCCESS mail from
0day robot before I push code to tip. If the SUCCESS is unreliable, this
is not good.
