Hi Linus,

FWIW, I've been working with Andreas on this and have tested it quite
extensively, although only with gfs2. I've tested it with numerous
scenarios, both stand-alone (xfstests as well as several other test
programs I have in my collection) and in a cluster with some very heavy
duty cluster coherency tests. My testing is nearly complete, but not
quite.

Regards,
