| D | Kconfig.debug | 1127 This feature enables tracking lock contention points
1131 This also enables lock events required by "perf lock",
1133 If you want to use "perf lock", you also need to turn on
1136 CONFIG_LOCK_STAT defines "contended" and "acquired" lock events.
1147 bool "Spinlock and rw-lock debugging: basic checks"
1195 This feature will check whether any held lock (spinlock, rwlock,
1198 vfree(), etc.), whether a live lock is incorrectly reinitialized via
1199 spin_lock_init()/mutex_init()/etc., or whether there is any lock
1217 If you say Y here, the lock dependency engine will do
1239 lock debugging then those bugs wont be detected of course.)
