Subject: Re: [PATCH v8 00/21] Compile-time stack validation
Date: Tue, 11 Aug 2015 16:31:07 -0500	[thread overview]
Message-ID: <55CA699B.4070809@canonical.com> (raw)

Josh,

I've applied and tried to build your patchset against the latest
mainline kernel with the following config:
http://paste.ubuntu.com/12058017/

I can build if I disable CONFIG_STACK_VALIDATION, then re-enable it
after all objects are already built, so this seems like it should be
resolvable in Makefiles. Any suggestions for debugging this?

Building from clean I get the following:
