gcc-plugins: randstruct: Update code comment in relayout_struct()
Update code comment to clarify that the only element whose layout is not randomized is a proper C99 flexible-array member. This update is complementary to commit 1ee60356c2dc ("gcc-plugins: randstruct: Only warn about true flexible arrays") Signed-off-by: "Gustavo A. R. Silva" <gustavoars@kernel.org> Link: https://lore.kernel.org/r/ZWJr2MWDjXLHE8ap@work Fixes: 1ee60356c2dc ("gcc-plugins: randstruct: Only warn about true flexible arrays") Signed-off-by: Kees Cook <keescook@chromium.org>
