解决方法。。

It seems to appear when CONFIG_SMP=N and CONFIG_DEBUG_SPINLOCK=N and
CONFIG_REISER4_DEBUG=N.

In this case, spinlock_t is an empty struct (see
include/linux/spinlock_types.h and
include/linux/spinlock_types_up.h). Then sizeof(spinlock_t) _is_ 0,
and this breaks some code like cassert calls from
fs/reiser4/spin_macros.h line 85 (FIELD is a spinlock_t) :
82 static inline void spin_ ## NAME ## _init(TYPE *x) \
83 { \
84 __ODCA("nikita-2987", x != NULL); \
85 cassert(sizeof(x->FIELD) != 0); \

86 memset(& x->FIELD, 0, sizeof x->FIELD); \

87 spin_lock_init(& x->FIELD.lock); \

88 } \
