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"
