The section mismatch analysis is always performed after a full kernel build, and enabling this option causes the following - additional steps to occur: + additional step to occur: - Add the option -fno-inline-functions-called-once to gcc commands. When inlining a function annotated with __init in a non-init function, we would lose the section information and thus the analysis would not catch the illegal reference.
