From 200a5c17677e1ee8b78382046f3748c9f5816281 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Mon, 3 Oct 2011 23:22:43 -0400 Subject: [PATCH] btrfs: find_and_setup_root error push-up find_and_setup_root BUGs when it encounters an error from btrfs_find_last_root, which can occur if a path can't be allocated. This patch pushes it up to its callers where it is already handled.
