From: Junxiao Bi junxiao.bi@oracle.com Subject: ocfs2: load global_inode_alloc
Set global_inode_alloc as OCFS2_FIRST_ONLINE_SYSTEM_INODE, that will make it load during mount. It can be used to test whether some global/system inodes are valid. One use case is that nfsd will test whether root inode is valid.
