Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt
Pull fscrypt updates from Eric Biggers: "First: Ted, Jaegeuk, and I have decided to add me as a co-maintainer for fscrypt, and we're now using a shared git tree. So we've updated MAINTAINERS accordingly, and I'm doing the pull request this time. The actual changes for v5.1 are: - Remove the fs-specific kconfig options like CONFIG_EXT4_ENCRYPTION and make fscrypt support for all fscrypt-capable filesystems be controlled by CONFIG_FS_ENCRYPTION, similar to how CONFIG_QUOTA works. - Improve error code for rename() and link() into encrypted directories. - Various cleanups" * tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt: MAINTAINERS: add Eric Biggers as an fscrypt maintainer fscrypt: return -EXDEV for incompatible rename or link into encrypted dir fscrypt: remove filesystem specific build config option f2fs: use IS_ENCRYPTED() to check encryption status ext4: use IS_ENCRYPTED() to check encryption status fscrypt: remove CRYPTO_CTR dependency
