X-Git-Tag: v0.6.6~149
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=4dd0d2f9cf055b4c8f525776adbca546d3405d66;hp=8c565d5f86789588dee14c01339dbead2d234502;p=kconfig-hardened-check.git

Skip normalize_cmdline_options() for the rodata cmdline parameter

Also fix the rodata check (change '1' to 'on').
