Last year it has extended kconfig coverage to all arch/*/configs/*.
Adding defconfigs there will auto add them to 0day. :)

If so, it should be considered a bug. Feel free to report such cases
to me.
If 0day failed to catch the error, it might be due to
- regressions in 0day itself -- it's still in active development,
in the past year I did 1k patches to 0day build/boot scripts and
2k patches to the follow up LKP (Linux Kernel Performance) tests.
- the "report once" logic, it's tricky and can possibly hide issues
- failed bisect, rare but possible
- machine hang, network/disk fails, etc. maintenance incidents
"Loading" may add latency, however it's not the cause to miss errors.

0day has such report type. It will be sent after each git push (unless
you push too quickly) and it looks like this. Just drop me a note and
list the git trees/branches you wish to receive such notice emails.
