I need to get some WARN_ON output to help a developer figure out a
regression in 4.15. When I test the problem with kernels from Fedora
built rpms I get the output from WARN_ON, but they don't have a
debugging patch from the developer applied. When I build using make
(both Linus' tree and Boyer's tree) I don't get that output.
I'm guessing there is a config setting that isn't in the normal Fedora
config file or I need to force a gcc option or something. But I thought
someone here might just know what a need to know. Otherwise I'll try to
figure it out from the spec file, but my memory of the kernel spec file
is that it is complicated and it might not be easy to figure out what
I'm looking for.
Thanks.
