It's in the ext4 master branch so it's queued to be pushed during the
next merge window, and then it would go into the 2.6.39.x stable
series.  So it didn't fall through the cracks; it was just a question
of whether to push late in the rc series, or waiting until the merge
window and then backporting to 2.6.39 stable.  Basically I got the
patch in -rc5, and at that point, given that the vast majority of the
file systems are 4k blocksize on x86, and most Power and Itanic users
are using distribution kernels (and that's a very small number
anyway), I decided not to push it to Linus at that point.

It's a judgement call; and I could have gone the other way; it was
very much a 49/51 sort of decision.
