ocfs2: return -EROFS to mount.ocfs2 if inode block is invalid
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 then mount again. 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.
