hm, it's bad for at least one other reason as well (which is probably
unrelated to this crash):
/*
* Currently fastpath is not supported if preemption is enabled.
*/
#if defined(CONFIG_FAST_CMPXCHG_LOCAL) && !defined(CONFIG_PREEMPT)
#define SLUB_FASTPATH
#endif
such !PREEMPT exceptions tend to show "i didnt want to think too hard
about the preemptible case so just turn it off" thinking.
Also, why isnt this "SLUB_FASTPATH" flag done in the Kconfig space?
