unpack_orig

函数名称：pack_orig_pfns - Set bits corresponding to given PFNs in a memory bitmap.*@bm: Memory bitmap.*@buf: Area of memory containing the PFNs.* For each element of the array pointed to by @buf (1 page at a time), set the* corresponding bit in @bm.

函数原型：static int unpack_orig_pfns(unsigned long *buf, struct memory_bitmap *bm)

返回类型：int

参数：

类型	参数	名称
unsigned long *	buf
struct memory_bitmap *	bm

以j小于PAGE_SIZE除sizeof(long)循环

2222

如果此条件成立可能性小(为编译器优化)(buf[j] == Data types related to memory bitmaps)则退出

2226

page_key_memorize(buf + j)

2228

如果pfn_valid(buf[j])且memory_bm_pfn_present(bm, buf[j])则memory_bm_set_bit(bm, buf[j])

2230

否则返回:负EFAULT

2234

返回:0
