This isn't technically a regression, since the warning is simply
complaining about something that apparently ext4 has been doing for a
long time, which is that it allocates some very large order data
buffers. So the change referenced simply printed a warning message
that complained about the fact.

The actual problem will be fixed in 2.6.32, as we no longer allocate
the big data buffers at mount time.
