[Ocfs2-users] versions, and more

[Sunil Mushran]

OCFS2 included in 2.6.18 does not have the shared writeable mmap nor
inline data nor sparse files. The first two should be useful in your
use-case.

We are currently backporting all those features to el5 (2.6.18).

Hopefully, we'll have something for general testing in the next
month.
