But, oddly, it _is_ the default for mke2fs -t ext4,
which really threw me for a loop recently.

I though my system had locked up when suddenly everything
went dead for a very long time (many minutes) while installing a new system.

Then I figured out what was going on.
I really believe that "-K" should be the _default_ for mke2fs,
as otherwise lots of other people probably also wonder
if Linux is killing their SSD at system install time..
