References : http://marc.info/?l=linux-kernel&m=125754907413892&w=4This 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.
