From: John Hubbard <jhubb...@nvidia.com> For the !CONFIG_PROVE_LOCKING case, the "class" variable is left unused. Rather than tease apart the functionality in lockdep_stats_show(), where class is used to increment up to 15 local variables, this patch merely adds yet another ifdef to fix the build warning.
