KASAN and KCSAN are mutually exclusive on 7.0-rc3 kernel (lib/Kconfig.kcsan: 'depends on ... !KASAN'). User picked KASAN first. This script applies the KCSAN-only config delta on top of the lockdep base for the follow-up build, so the KCSAN config survives session-compacting. Run AFTER the KASAN-pass test cycle completes, IF KASAN comes up silent on the GPU-compositor wedge test. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
