函数名称:_integrity_alloc - Allocate integrity payload and attach it to bio*@bio: bio to attach integrity metadata to*@gfp_mask: Memory allocation mask*@nr_vecs: Number of integrity metadata scatter-gather elements* Description: This function prepares a bio for
函数原型:struct bio_integrity_payload *bio_integrity_alloc(struct bio *bio, gfp_t gfp_mask, unsigned int nr_vecs)
返回类型:struct bio_integrity_payload
参数:
类型 | 参数 | 名称 |
---|---|---|
struct bio * | bio | |
gfp_t | gfp_mask | |
unsigned int | nr_vecs |
45 | 如果非bs或非mempool_initialized( & bio_integrity_pool)则 |
47 | inline_vecs等于nr_vecs |
48 | 否则 |
53 | 如果此条件成立可能性小(为编译器优化)(!bip)则返回:错误号 |
58 | 如果nr_vecs大于inline_vecs则 |
59 | idx等于0 |
61 | bip_vec等于bvec_alloc(gfp_mask, nr_vecs, & idx, & bvec_integrity_pool) |
67 | 否则 |
72 | parent bio 等于bio |
73 | data integrity 等于bip |
76 | 返回:bip |
77 | err : |
79 | 返回:错误号 |

bio_integrity_prep | _integrity_prep - Prepare bio for integrity I/O*@bio: bio to prepare* Description: Checks if the bio already has an integrity payload attached.* If it does, the payload has been generated by another kernel subsystem,* and we just pass it through |
bio_integrity_clone | _integrity_clone - Callback for cloning bios with integrity metadata*@bio: New bio*@bio_src: Original bio*@gfp_mask: Memory allocation mask* Description: Called to allocate a bip when cloning a bio |
