Subject: [PATCH] enable XFS write barrier

I found out that the q->ordered is not being set properly on XFS.

I'm testing the write barrier support of XFS.
I run the test on kernel 2.6.16-rc1-git4.
but I found out that the "-o barrier" option is automatically disabled
in my environment.
For this reason I could not test the write barrier's execution path.

The error message in "/var/log/messages" is:
Filesystem "sdb1": Disabling barriers, not supported by the underlying device

This patch fixes these bugs.

Best regards,

Tetsuo Takata
