From 4f024f3797c43cb4b73cd2c50cec728842d0e49e Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Fri, 11 Oct 2013 15:44:27 -0700 Subject: block: Abstract out bvec iterator MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Immutable biovecs are going to require an explicit iterator. To implement immutable bvecs, a later patch is going to add a bi_bvec_done member to this struct; for now, this patch effectively just renames things.
