There are ext4-related fixes in the 19->20 patches.  There are no ext4
related patches in 20->21, so whether or not you do this is optional
(from the perspective of applying this patch).

Yes, same as before.  I will note that there were some enhancements
and some lower-priority bug fixes that don't get backported to 2.6.27
series, since sometimes it is extremely difficult to backport things
as far as 2.6.27.  So if your goal is to use this in production,
2.6.29 will almost certainly be a better bet.  The number of people
who test the 2.6.27 backports of ext4 are also much smaller.  We
provide it as a service those who for whatever reason refuse to update
to newer kernels, but it's hard for me to offer guarantees.
