Thanks for your appreciations, Luis!

I'd be glad to answer questions and more importantly, collect
feedbacks on where and how to improve the 0-day infrastructure.

There are 2 major parts in 0-day: build tests and runtime tests.
While build tests will be continuously improved, there may be a lot
more to be desired for runtime tests, which should be my main focus
in the coming year.

Sure if there are interests.

0-day tries to monitor as many git trees as possible, so that fresh
code can be tested before they land maintainer trees and linux-next.
To achieve better early code coverage, we periodically check if there
are new git trees showing up in git.kernel.org, in mainline git log
or mentioned in LKML emails. And add the newly discovered ones
unsolicited. :)

That said, it's still possible errors hit linux-next. Sometimes it may
be due to bug in 0-day or temporarily out of service. The solution
would be to improve 0-day system's stability and add more self-tests
to the system. Quick feedbacks about build/boot errors missed by 0-day
would also be highly appreciated.

Thanks,
