Question about current->namespace and check_mnt()

I have a specific namespace.c question:
I really like to know what the purpose of check_mnt() is in
namespace.c. In standard kernels you can't enter another process'
namespace so I don't see how check_mnt() can _ever_ fail. Can it
fail, or in other words, what is the purpose of that check?
And if it can't fail, is there really a need for current->namespace, or
can it just be removed?
Also, I would think the current process' rootmnt->mnt_namespace would
adequately define the "current process namespace", so making
current->namespace redundant in that way. Is that right?
