    One nice thing about ChaCha20 (and the Salsa20 family) is that you can seek to any point in the plaintext in constant time. This could lead to much better random access performance than dm-crypt with AES.

      Equally true of AES-GCM, which is the main alternative to ChaCha20-Poly1305. Dmcrypt cannot use such modes due to being transparent full disk encryption. FS specific code can.

        I'm very excited with this file system. And am hoping it makes it into mainline soon.

          Why ChaCha? Is it faster than AES using AES-NI?

              ChaCha among the secure ones in one of the fastest for non-AES-accelerated CPUs

                no, aes-ni is faster than chacha but if aes-ni is not supported chacha is faster
