EXT4 In Linux 4.1 Adds File-System Level Encryption
Earlier this month we wrote about the newly-published patches for EXT4 encryption support coming out of Google and intended to land in the next major release of Android. Those patches for file-system-level encryption will now be landing upstream with the Linux 4.1 kernel update.
Besides this native encryption support for EXT4, the rest of the updates for this merge window pull request equate to mainly fixes. More details via the pull request itself.
