ANDROID: ext4 crypto: Disables zeroing on truncation when there's no key
When performing orphan cleanup on mount, ext4 may truncate pages.
Truncation as currently implemented may require the encryption key for
partial zeroing, and the key isn't necessarily available on mount.
Since the userspace tools don't perform the partial zeroing operation
anyway, let's just skip doing that in the kernel.
This patch fixes a BUG_ON() oops.
