For the moment, I've left it as the same behaviour as for mount(2) since
mount(2) now uses the same mechanism internally and we aren't permitted to
break userspace.

I would like to add at least one flag to stipulate that, in the case of an
incompatible collision, you can get a failure - but defining what is meant by
incompatible isn't necessarily trivial, and would vary by filesystem *and* the
LSM.

However, I don't want to start reengineering everything this close to the
merge window and we don't really need it immediately.
