Any function with "check" in the name makes my teeth ache. "check" what? And the name doesn't carry any connotation of the return value's meaning. eg, "check_the_cheese()" versus "cheese_is_fresh()". The latter name tells you what is being checked and it tells you what a "true" return value means. Also, the dang function isn't documented. Also, why is mremap_to() calling mremap_vma_check() without testing its return value? mremap_vma_check() doesn't actually alter anything, does it? If it does then it's misnamed.
