All that I found was the commit to add fsconfig to the kernel tree:

commit ecdab150fddb
Author: David Howells <dhowells@redhat.com>
Date: Thu Nov 1 23:36:09 2018 +0000

vfs: syscall: Add fsconfig() for configuring and managing a context

and the lore archive for its discussion:
https://lore.kernel.org/all/153313723557.13253.9055982745313603422.stgit@warthog.procyon.org.uk/

plus David's userspace man page addition for it:
