Hi Tyler,

thanks for your note.  It is nice to know that user-space devs read
this list, too :-)

I haven't written any instructions on getting ecryptfs-utils working
in Android yet, but this is something I would like to do.  Importing
keyutils into aosp is a snap, but not so much for ecryptfs-utils.

Unfortunately, the changes I made aren't very merge-friendly, but I
can reformat them inside appropriate if-def blocks (i.e. #ifdef
ANDROID... #endif).  I could then send you a patch (or point you to a
git repo) based on the 103 release.

sound ok?
