It only updates per-file feature flags. And all the ioctl which change
behaviour depending upon these flags (they're all kms features) do
_not_ hold the BKL. Therefor this is pure cargo-cult and can be
removed.
Note that there's a risk that the ioctl will behave inconsistently,
but that's ok. The only thing it's not allowed to do is oops the
kernel, and from an audit all places are safe.
