From fb5cbe9efd741b16e72133613747f76490bbecd3 Mon Sep 17 00:00:00 2001 From: Joel Becker Date: Wed, 28 Oct 2009 22:28:24 -0700 Subject: ocfs2: Return -EINVAL when a device is not ocfs2. In case of non-modular kernels the root filesystem is mounted by trying several filesystems. If ocfs2 was tried before the actual filesystem type, the mount would fail because ocfs2_sb_probe() returns -EAGAIN instead of -EINVAL. ocfs2 will now return -EINVAL properly.
