so, I tried QA suite 022 three times using the CVS kernel and
cmds which were updated on last friday. Then, all of them have
been passed :-) I'll try more tonight.

I would like to know that whether it is correct way or
workaround to dump the XFS file system which requires preceding
unmount and mount, not only for QA suite but also on a
Could you explain me about this?
