From 0d4b0463011de06288d8ca80a873a97a7d99a948 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 24 Jan 2020 09:32:53 -0500 Subject: [PATCH] btrfs: export and rename free_fs_info We're going to start freeing roots and doing other complicated things in free_fs_info, so we need to move it to disk-io.c and export it in order to use things lik btrfs_put_fs_root().
