    SubjectRe: [PATCH 11/11] Use unreachable() in asm-generic/bug.h for !CONFIG_BUG case.

    Brian was talking BUG_ON().

    And the existing !CONFIG_BUG BUG_ON() is actually set up so that gcc will
    just optimize it away entirely (yet give the same compile-time warnings as
    the "real" BUG_ON() does).

    Changing it to "if (cond) unreachable()" is likely to generate _more_
    code, which is against the whole point of wanting to disable CONFIG_BUG.
