[Ocfs2-devel] [PATCH 2/3] Ocfs2: Teach local-mounted ocfs2 to handle unwritten_extents correctly.

[Sunil Mushran]

Acked-by: Sunil Mushran <sunil.mushran at oracle.com>

BTW, this affects the o2cb stack too. Not just local mounts.

Also, cc stable at kernel.org as this problem was introduced in
2.6.38 by 2fe17c10.
