You can run make with "C=1", which will run sparse on all files that are rebuilt during that make run. For example, if I fully build the kernel and then revert commit cb5172d96d16df72db8b55146b0ec00bfd97f079, I get: $ make [...] C=1 [...] CHECK [...]/kernel/audit.c [...]/kernel/audit.c:218:14: error: incompatible types in comparison expression (different address spaces): [...]/kernel/audit.c:218:14: struct auditd_connection [noderef] <asn:4> * [...]/kernel/audit.c:218:14: struct auditd_connection * (...and a lot more errors like this + 2 different warnings) And when I un-revert it again, I get only the 2 warnings. -- Ondrej Mosnacek <omosnace at redhat dot com> Software Engineer, Security Technologies Red Hat, Inc. -- Linux-audit mailing list Linux-audit@redhat.com https://www.redhat.com/mailman/listinfo/linux-audit
