what to do with a private BUILD REGRESSION report ?

what to do with a private BUILD REGRESSION report ?

I recently (3 hrs ago) got a report from lkp

[jimc:dd-drm-next] BUILD REGRESSION 72004a480e5609bb441794ac5e75fc2aa95ca500

Why is this a private email, and not sent to kbuild-all too ?
It seems counter to convention,
and all my other brown-bag errors are splayed out for ridicule ;-)

and more importantly...
why is it different than the more public reports ?
did this revision get further than previous ones ? 
what milestone did it reach ?


As to its contents

Error/Warning in current branch:

drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_debug.c:63:54: error: expected ')' before string constant
lib/dynamic_debug.c:1227:52: error: invalid use of undefined type 'struct module'

possible Error/Warning in current branch:

drivers/gpu/drm/drm_print.c:62:52: error: expected ')' before string constant
lib/dynamic_debug.c:1227:52: error: incomplete definition of type 'struct module'

it looks like a proper compile err,
why is it reported this way, and not like others Ive received (this from 8/5)
[kbuild-all] [jimc:dd-drm-next 7/8] drivers/gpu/drm/drm_print.c:64:41: error: expected ')' before string constant
those others include triggering .config, and cross compile script

is the difference that the error is on 8/8, after I shuffled patch order ?

lkp ran the patchset on a lot of configs,
are these configs available for download ?
If they are, could you add a link to the report ?

thanks,
Jim

Hi Jim,

Sorry for the late.

kbuild-all mailing list is used to archive the build reports,
BUILD REGRESSION is a summary report for the author or owner.

we limited the report number for the same commit to avoid too many noise.

it should be not related to the patch order.

we only attach the config on the build report, there's many configs 
mentioned in this BUILD REGRESSION report, we don't have a link to 
download all of them.
