Not really. Last time I checked (a few months ago), there were still
some scary looking bugs in ext4 that concerned me, and I've seen one
difficult to explain bit of corruption on it. Lots of these bugs had
been fixed in the mainline Linux kernel, but I wasn't sure they'd all
been backported to the sort of distributions my customers run. I expect
to re-evaluate RHEL6 to see how it's doing soon, just haven't had
time/requests for it.
