    Agreed, using vmalloc()/vfree() isn't a perfect solution, but at least
    the approach of kmalloc() for small allocations and vmalloc() for
    larger allocations solves the current problem (reading tasks/procs
    files can fail due to lack of contiguous kmalloc memory) without
    introducing overhead in the typical case.
