[PATCH 09/11] block: mark the bio as cloned in bio_iov_bvec_set

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



bio_iov_bvec_set clones the bio_vecs from the iter, and thus should be
treated like a cloned bio in every respect.  That also includes not
touching bi_max_vecs as that is a property of the bio allocation and not
its current payload.
