From 23fa76b0ba78b7d84708d9ee683587d8a5bbceef Mon Sep 17 00:00:00 2001 From: Stefan Behrens Date: Fri, 23 Aug 2013 10:34:43 +0200 Subject: [PATCH] Btrf: cleanup: don't check for root_refs == 0 twice btrfs_read_fs_root_no_name() already checks if btrfs_root_refs() is zero and returns ENOENT in this case. There is no need to do it again in three more places.
