Ah, I unconditionally deref lockdep_stats there. Ok, will
fix.

I'm not home yet, but once I can, will send the fix asap.

Thanks.

this one is causing:

kernel/lockdep.c:2306: error: 'lockdep_stats' undeclared (first use in this function)
kernel/lockdep.c:2306: error: (Each undeclared identifier is reported only once
kernel/lockdep.c:2306: error: for each function it appears in.)

with these settings:

CONFIG_LOCKDEP=y
# CONFIG_LOCK_STAT is not set
# CONFIG_DEBUG_LOCKDEP is not set
# CONFIG_DEBUG_SPINLOCK_SLEEP is not set
# CONFIG_DEBUG_LOCKING_API_SELFTESTS is not set

Thanks,

	Ingo

[Frederic Weisbecker]

Ingo,

Please pull the core/locking branch that can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git
	core/locking

Note there is also a merge of v2.6.34-rc6 because these patches
depend on older per cpu updates.

Thanks,
	Frederic
