Subject: [GIT PULL] fscrypt updates for 4.16

Note: there will be a merge conflict; please just take the chunk
which calls fscrypt_encrypt_symlink() from the fscrypt tree.  This
will end up dropping the kzalloc() -> f2fs_kzalloc() change, which
means the fscrypt-specific allocation won't get tested by f2fs's
kmalloc error injection system; which is fine.

The ubifs and f2fs changes have been reviewed by their respective
maintainers and I got their approval to run all of these changes
through the fscrypt tree.
