From 8ddc7d9cd0a00062247c732b96386ec2462bdbc7 Mon Sep 17 00:00:00 2001 From: Jan Schmidt Date: Mon, 13 Jun 2011 20:02:58 +0200 Subject: [PATCH] btrfs: add mirror_num to extent_read_full_page Currently, extent_read_full_page always assumes we are trying to read mirror 0, which generally is the best we can do. To add flexibility, pass it as a parameter. This will be needed by scrub fixup code.
