From f73a1c7d117d07a96d89475066188a2b79e53c48 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Tue, 25 Sep 2012 15:05:12 -0700 Subject: block: Add bio_end_sector() Just a little convenience macro - main reason to add it now is preparing for immutable bio vecs, it'll reduce the size of the patch that puts bi_sector/bi_size/bi_idx into a struct bvec_iter.
