btrfs: tree-checker: Replace root parameter with fs_info
When inspecting the error message with real corruption, the "root=%llu" always shows "1" (root tree), instead of the correct owner. The problem is that we are getting @root from page->mapping->host, which points the same btree inode, so we will always get the same root. This makes the root owner output meaningless, and harder to port tree-checker to btrfs-progs. So get rid of the false and meaningless @root parameter and replace it with @fs_info. To get the owner, we can only rely on btrfs_header_owner() now. Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
