invalidate_bh

函数名称：validate_bh_lrus() is called rarely - but not only at unmount.* This doesn't race because it runs in each cpu either in irq* or with preempt disabled.

函数原型：static void invalidate_bh_lru(void *arg)

返回类型：void

参数：

类型	参数	名称
void *	arg

b等于Must be an lvalue. Since @var must be a simple identifier,* we force a syntax error here if it isn't.(bh_lrus)

以i小于Per-cpu buffer LRU implementation. To reduce the cost of __find_get_block().* The bhs[] array is sorted - newest buffer is at bhs[0]. Buffers have their* refcount elevated by one when they're in an LRU. A buffer can only appear 循环

1415

brelse(bhs[i])

1416

bhs[i] = NULL

1418

The weird & is necessary because sparse considers (void)(var) to be* a direct dereference of percpu variable (var).(bh_lrus)
