Date: Thu, 17 Aug 2017 17:57:39 +0900 From: Byungchul Park <byungchul.park@....com> To: peterz@...radead.org, mingo@...nel.org Cc: linux-kernel@...r.kernel.org, kernel-team@....com Subject: [PATCH v3 1/3] lockdep: Make LOCKDEP_CROSSRELEASE configs all part of PROVE_LOCKING Crossrelease added LOCKDEP_CROSSRELEASE and LOCKDEP_COMPLETE configs. It makes little sense to enable them when PROVE_LOCKING is disabled. Make them non-interative option and all part of PROVE_LOCKING.
