t10_pi_type1_complete

Name:10_pi_type1_complete - prepare PI prior returning request to the blk layer*@rq: request with PI that should be prepared*@nr_bytes: total bytes to prepare* For Type 1/Type 2, the virtual start sector is the one that was

Proto:static void t10_pi_type1_complete(struct request *rq, unsigned int nr_bytes)

Type:void

Parameter:

Type	Parameter	Name
struct request *	rq
unsigned int	nr_bytes

185

intervals = nr_bytes >> interval_exp

186

tuple_sz = tuple_size

187

ref_tag = t10_pi_ref_tag(rq)

191

bip = bio_integrity(bio)

192

virt = bip_get_seed(bip) & 0xffffffff

196

bip_for_each_vec(iv, bip, iter)

200

pmap = kmap_atomic(bv_page)

201

p = pmap + bv_offset

202

When j < bv_len && intervals cycle

203

pi = p

205

If be32_to_cpu(Target LBA or indirect LBA ) == ref_tag Then Target LBA or indirect LBA = cpu_to_be32(virt)

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.(pmap)
