103 结构体包含了该 bio 的完整性负载。本质上，bip 是一个精简版的 struct bio，其
108 性保护。该函数会分配并附加一个 bip 到该 bio 上。
112 调用 bio_free() 会自动释放bip。
167 `struct bip * bio_integrity_alloc(bio, gfp_mask, nr_pages);`
177 将包含完整性元数据的一页附加到已有的 bio 上。该 bio 必须已有 bip，
181 中可能会被修改！完整性元数据中的第一个引用标签必须等于 bip->bip_sector。
183 只要 bip bio_vec array（nr_pages）有空间，就可以继续通过

| H A D | data-integrity.rst | 138 pointer to a struct bip which contains the bio integrity payload.
139 Essentially a bip is a trimmed down struct bio which holds a bio_vec
145 bip to the bio.
150 bio_free() will automatically free the bip.
216 `struct bip * bio_integrity_alloc(bio, gfp_mask, nr_pages);`
228 bio. The bio must have an existing bip,
235 integrity metadata must have a value of bip->bip_sector.
238 there is room in the bip bio_vec array (nr_pages).
