From 6cf66b4caf9c71f64a5486cadbd71ab58d0d4307 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Mon, 22 Dec 2014 12:48:42 +0100 Subject: fs: use helper bio_add_page() instead of open coding on bi_io_vec Call pre-defined helper bio_add_page() instead of open coding for iterating through bi_io_vec[]. Doing that, it's possible to make some parts in filesystems and mm/page_io.c simpler than before.
