There is no patch series (for both kernel & ldiskfs) available for
2.6.27
and we will likely not provide one before we support 2.6.30, since we
need a stable ext4 tree for ldiskfs. ext4 in SLES11 is quite up to
date, that's why we can afford to support servers on this kernel.

What kernel did you use to compare the performance?
FYI, we removed the intent patches (used on the client side)
for kernels >= 2.6.16. Basically, this means that patchless
client is the default now, even if you use the patched kernel.
