This is just wrong, the process that calls into the reg_mr is the process associated with the umem, and that does not have to be the same process that created the context. When this code was first written mmgrab() didn't exist, however these days we can just directly hold the mm_struct pointer in the umem and have no ambiguity when it comes to releasing the umem as to which mm it was associated with.
