Well, a patch exists for it that will be merged into 2.6.38.

I'm not going to make it be the default for 2.6.38, since it's fairly
late in the -rc features. People who want it can explicitly enable it
using the mount option mblk_io_submit, though. (And let me know your
success stories! :-) I will be enabling it as the default in
2.6.39-rc1.
