From 0045d61b5b7470f7228b35e1ab7139119e249503 Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Fri, 21 Dec 2012 20:23:40 +0000 Subject: [PATCH] dm raid1: dont use map_context Don't use map_info any more in dm-raid1. map_info was used for writes to hold the region number. For this purpose we add a new field dm_bio_details to dm_raid1_bio_record. map_info was used for reads to hold a pointer to dm_raid1_bio_record (if the pointer was non-NULL, bio details were saved; if the pointer was NULL, bio details were not saved). We use dm_raid1_bio_record.details->bi_bdev for this purpose. If bi_bdev is NULL, details were not saved, if bi_bdev is non-NULL, details were saved.
