From: Junxiao Bi <junxiao.bi@xxxxxxxxxx> 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.
