It's harmless.

It's really a warning that says: the mm that you allocated a new LDT for
may have multiple users, and while the LDT is added to all of them, we
don't guarantee _when_ the other users will actually see the LDT.

It so happens that the other users are probably just something like
"top" or similar, that increment the MM count to make sure that the MM
doesn't go away while they get information about the process. And those
users don't care about the LDT in the least.
