The lock validator gives me this (latest -mm and 2.6.18-rc6): ===================================== [ BUG: bad unlock balance detected! ] ------------------------------------- swapper/0 is trying to release lock (resource_lock) at: [<0000000000042842>] request_resource+0x52/0x88 but there are no more locks to release! The reason is that the BUILD_LOCK_OPS macros in kernel/lockdep.c don't contain any of the *_acquire calls, while all of the _unlock functions contain a *_release call. Hence I get immediately unbalanced locks. CONFIG_PREEMPT, CONFIG_SMP, !CONFIG_PROVE_LOCKING, CONFIG_DEBUG_LOCK_ALLOC, and CONFIG_LOCKDEP will generate this code. Found this will debugging some random memory corruptions that happen when CONFIG_PROVE_LOCKING and CONFIG_PROFILE_LIKELY are both on. Switching both off or having only one of them on seems to work. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
