This looks good.

Thanks for doing these!  They seem like they would be very useful.
Hopefully, once we get trim support plumbed all the way down, it won't be
necessary to issue the erase manually.

I do have a few comments:

 - The patches should be generated against head, since they would be
   committed there first and merged back.  (They don't apply cleanly to
   head.)

 - There are a number of style issues in the patches:
	- Lines longer than 80 characters
	- Spaces/formatting problems (e.g. at the beginning of
	  atasecurity_erase()).
	- The prevailing style of the file isn't followed for line
	  continuations.  (It isn't always KNF, either.)

 - I'm not really a fan of getopt_long.  There are lots of password
   arguments, how about turning those into '-p foopasswd=bar' instead?

Anyway, if you could, please address those things and send me the diffs.

Thanks!

Ken
