linux-2.6_2.6.18.orig.tar.gz + linux-2.6_2.6.18-7.diff.gz

Looks like stride parameter changes on-disk layout by adjusting block and
inode bitmap locations. It does not directly affect file system to device
driver communications.

I quickly looked at the source. To me it looked like that same improvements
or regressions should apply for both ext3->RAID5 and ext3->loop-AES->RAID5.
