From 2c30c71bd653afcbed7f6754e8fe3d16e0e708a1 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Thu, 7 Nov 2013 12:20:26 -0800 Subject: block: Convert various code to bio_for_each_segment() With immutable biovecs we don't want code accessing bi_io_vec directly - the uses this patch changes weren't incorrect since they all own the bio, but it makes the code harder to audit for no good reason - also, this will help with multipage bvecs later.
