After this patch, when error, ocfs2_fill_super doesn't take care to
release resources which are allocated in ocfs2_initialize_super.

Or just set "osb" to NULL is enough to keep code consistency.
Other looks good. Once it is resolved, feel free to add:

In the front of ocfs2_initialize_super, the sb->s_fs_info is set to osb.
So set osb to NULL is not enough, sb->s_fs_info still keep wild pointer.
The caller (ocfs2_fill_super) will fetch the wild value from OCFS2_SB(sb).

Another question: do I need to resend v3 patch with "Reviewed-by: Joseph Qi ..."

Thanks,
Heming

IC, you are right.

Not needed. And Andrew Morton already has added it into -mm tree.
