This series introduces a new namespace for binfmt_misc.

This seems conceptually quite reasonable, but I'm wondering if the
number of namespace types is getting out of hand given the current
API.  Should we be considering whether we need a new set of
namespace
creation APIs that scale better to larger numbers of namespace
types?

Yes, we need something to increase the maximum number of namespace
types
because this is the last bit in the clone() flags and the time
namespace
has already preempted it.

Yeah, there is this last CLONE_* flag..
I tried to use that 0x1000 flag for something like CLONE_EXTENDED with
all parameters on the stack, but not sure that's reasonable and maybe
someone will suggest a better solution.
All those different clone() ABI (how many parameters to supply and in
which order do not help much).
