For supported file systems, fscrypt[1] allows you to encrypt at a directory level.
It has no trusted key integration yet, which is something I am trying to upstream
in parallel to this series, so I eventually can use fscrypt together with CAAM-backed
trusted keys on an unpatched kernel.

If it interests you, I described[2] my CAAM+ubifs+fscrypt use case in the
discussion thread on my fscrypt-trusted-keys v1. Jan, a colleague of mine, held a
talk[3] on the different solutions for authenticated and encrypted storage, which
you may want to check out.

I'd really appreciate feedback here on the the CAAM parts of this series, so this can
eventually go mainline.

Thanks,
Ahmad
