From 3ec706c831d4c96905c287013c8228b21619a1d9 Mon Sep 17 00:00:00 2001 From: Stefan Behrens Date: Mon, 5 Nov 2012 15:46:42 +0100 Subject: Btrfs: pass fs_info to btrfs_map_block() instead of mapping_tree This is required for the device replace procedure in a later step. Two calling functions also had to be changed to have the fs_info pointer: repair_io_failure() and scrub_setup_recheck_block().
