This patch series adds support for Inline Encryption to fscrypt, f2fs
and ext4. It builds on the inline encryption support now present in
the block layer, and has been rebased on v5.8-rc1.

Patch 1 introduces the SB_INLINECRYPT sb options, which filesystems
should set if they want to use blk-crypto for file content en/decryption.

Patch 2 adds inline encryption support to fscrypt. To use inline
encryption with fscrypt, the filesystem must set the above mentioned
SB_INLINECRYPT sb option. When this option is set, the contents of
encrypted files will be en/decrypted using blk-crypto.

Patches 3 and 4 wire up f2fs and ext4 respectively to fscrypt support for
inline encryption, and e.g ensure that bios are submitted with blocks
that not only are contiguous, but also have contiguous DUNs.
