I'm not sure all the blank lines you're suggesting would be an improvement.
The ones in fscrypt_provisioning_key_preparse() might make sense though.

I'm working on an xfstest for this:

	https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/xfstests-dev.git/commit/?h=fscrypt-provisioning&id=24ab6abb7cf6a80be44b7c72b73f0519ccaa5a97

It's not quite ready, though.  I'll post it for review when it is.

Someone is also planning to update Android userspace to use this.  So if there
are any issues from that, I'll hear about it.
