rmk - Russell King
he writes kernel patches for the ARM linux kernel it seems.
as for the crypt1
As you can guess thats some kernel patch for crypto support, but i cant decide which one it is yet.
There are several encrypting file systems out there but as far as i can tell, unless that little set of sectors is a hidden disk parition they somehow force mount as an encrypted filesystem I dont think thats where this -crypt stuff came from.
