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
