But that's not what kernel versions have been for. They aren't for feature
bumps, etc. They are for LKM compatability. Since adding UFS2 didn't
change how well LKMs do or don't hook into the kernel, there was no need
to bump the version.

Adding a tag might have been good, but since the code had survived a few
weeks of hard testing from Frank, I can see that there didn't seem to be
much need.

Take care,
