From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

There is dmcrypt that basically does what you want. IDK if the implementation is in kernel space though. It works through /dev/mapper if that matters.
I'm too high to understand encrypt but it sounds close to what I want. I'll have to research it later
Look up docs for cryptsetup which is the simplest way to use it. The Debian installer (and maybe others) can set it up for you automatically as well.
