I started using it in 2.6.30. The only changes since 2.6.30 that I've
noticed are changes to prevent data damage due to lack of journal replay
after an abrupt power loss during a journal wraparound (that was 2.6.32,
a fix to a bug exposed by a change in 2.6.31, but the fix will have been
backported to affected distro kernels), fairly small block allocator
improvements, and changes to fix the ioctl used by the yet-unwritten
ext4 online defragmenter.

Any halfway recent kernel should be fine. The class of bugs that are now
being squashed are terribly rare and hard to trip over. I'd call it
reliable.

(I'm afraid I can't remember much about 2.6.26, it was so long ago.  I'm
astonished that half the systems at work are still running a deformed
RHEL-patched-to-hell 2.6.9!)
