Thanks, that eliminated almost all of the warnings. I'm still seeing this: WARNING: vmlinux.o(.text+0x1087e7): Section mismatch in reference from the function rebind_subsystems() to the variable .init.rodata.str:__func__.4400 The function rebind_subsystems() references the variable __initconst __func__.4400. This is often because rebind_subsystems lacks a __initconst annotation or the annotation of __func__.4400 is wrong. WARNING: vmlinux.o(.text+0x13789d): Section mismatch in reference from the function register_ftrace_export() to the variable .init.rodata.str:__func__.4251 The function register_ftrace_export() references the variable __initconst __func__.4251. This is often because register_ftrace_export lacks a __initconst annotation or the annotation of __func__.4251 is wrong. WARNING: vmlinux.o(.text+0x139d24): Section mismatch in reference from the function tracepoint_printk_sysctl() to the variable .init.rodata.str:__func__.4251 The function tracepoint_printk_sysctl() references the variable __initconst __func__.4251. This is often because tracepoint_printk_sysctl lacks a __initconst annotation or the annotation of __func__.4251 is wrong. I haven't taken a close look yet, but I assume these are from the const strings in these functions? -Kees -- Kees Cook Nexus Security -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
