From 3a281f946640542a7a7372f436e101ee1fbc4c97 Mon Sep 17 00:00:00 2001 From: Bob Copeland Date: Thu, 28 May 2015 15:44:32 -0700 Subject: [PATCH] omfs: set error return when d_make_root() fails A static checker found the following issue in the error path for omfs_fill_super: fs/omfs/inode.c:552 omfs_fill_super() warn: missing error code here? 'd_make_root()' failed. 'ret' = '0' Fix by returning -ENOMEM in this case.
