From 3a83f4677539bce8eaa2bca9ee9c20e172d7ab04 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Tue, 22 Nov 2016 08:57:21 -0700 Subject: block: bio: pass bvec table to bio_init() Some drivers often use external bvec table, so introduce this helper for this case. It is always safe to access the bio->bi_io_vec in this way for this case. After converting to this usage, it will becomes a bit easier to evaluate the remaining direct access to bio->bi_io_vec, so it can help to prepare for the following multipage bvec support.
