If metadata is corrupted such as 'invalid inode block', we will get
failed by calling 'mount()' and then set filesystem readonly as below:
ocfs2_mount
ocfs2_initialize_super
ocfs2_init_global_system_inodes
ocfs2_iget
ocfs2_read_locked_inode
ocfs2_validate_inode_block
ocfs2_error
ocfs2_handle_error
ocfs2_set_ro_flag(osb, 0); // set readonly
In this situation we need return -EROFS to 'mount.ocfs2', so that user
can fix it by fsck and mount again rather than doing meaningless retry.
In addition, 'mount.ocfs2' should be updated correspondingly as it only
return 1 for all errno. And I will post a patch for 'mount.ocfs2' too.
