返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct block_device * | bdev | |
struct dax_device * | dax_dev | |
sector_t | sector | |
size_t | size | |
struct page * | to | |
unsigned long | vaddr |
696 | id等于dax_read_lock() |
698 | 如果rc小于0则 |
699 | dax_read_unlock(id) |
700 | 返回:rc |
702 | vto等于kmap_atomic(to) |
704 | Prevent people trying to call kunmap_atomic() as if it were kunmap()* kunmap_atomic() should get the return value of kmap_atomic, not the page.(vto) |
