Will be when 2.6.29 hits F10.

F10 still had ext4 as a "hidden" fs option, remember, it was a bit more
of a test fs at that point.  We do make efforts to keep things working
well in F10 (Thanks esp. to Chuck!) but F10 ext4 wasn't expected to be
without some potential flaws.

In the larger picture, I have yet to hear a complaint about this sort of
buffered data loss on a crash on ext4 in Fedora.  At least no bugs have
been filed over it.

Remember guys, this is fedora-test-list; posting things like "does it
work?" or "I'm afraid it may not work so I'm not using it" here strikes
me as odd.  You can help root out these or issues by testing it, now,
before F11 goes gold.

Thanks,
