Commit Message
It was added on Linux 5.2 (24dcb3d90a1f67fe08c68a004af37df059d74005)
to start the process of preparing to create a superblock that will
then be mountable, using an fd as a context handle.

OK. Expecting FSOPEN_CLOEXEC and it is present. The flag does what we expect because something
has to close the fd that is attached to the mount context. Verified FSOPEN_CLOEXEC is the only
