[PATCH tip/core/rcu 04/17] rcu: Make rcu node arrays static const char * const

From: Paul E. McKenney
Date: Mon Jul 07 2014 - 18:41:14 EST


From: Fabian Frederick <fabf@xxxxxxxxx>

Those two arrays are being passed to lockdep_init_map(), which expects
const char *, and are stored in lockdep_map the same way.
