[ Upstream commit 025bcbde3634b2c9b316f227fed13ad6ad6817fb ]
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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
