Fixing the leak is far more important than the other five patches, and
we'll want to backport the leak fix into earlier kernels.  So the
bugfix patch should have been the first in the series!

So I've reordered the patches in that fashion and shall tag "mqueue:
fix mq_open() file descriptor leak on user-space processes" as needing
-stable backporting.

The patches apply and build OK with that reordering, but please do
double-check it, thanks.
