kernel 2.6.30 and ext4 file systems - nodelalloc still needed?
Is it true that one does not need the nodelalloc switch in the /etc/fstab to prevent data loss due to an ungraceful reboot/shutdown of an ext4 partition under the new 3.6.30 kernel?

You shouldn't need nodelalloc, yes.
ext4 2.6.30 has code in it that hacks around the most common problems with apps that write data assuming the filesystem exhibits ext3-like behavior. But it's up to you -- if you didn't notice any performance loss, why not keep it?

@Ranguvar - thanks for the reply. Suppose I can leave it but just wanted to get an opinion from a more experienced person as to the relevance of the nodelalloc flag w/ 2.9.30.

I removed nodelalloc on my partitions, too
