    Subject[PATCH tip/core/rcu 4/8] kernel: Removing undead ifdef CONFIG_DEBUG_LOCK_ALLOC
    Date
    From: Christian Dietrich <qy03fugy@stud.informatik.uni-erlangen.de>

    The CONFIG_DEBUG_LOCK_ALLOC ifdef isn't necessary at this point, because it is
    checked in an outer ifdef level already and has no effect here.
