Often, it is useful to first allocate a big chunk of memory before continuing to gradually allocate smaller chunks to cuase stress. For example, let's say that someone is trying to hit a certain memory limit of 5GB. In such a case, it is often useful to first allocate 4GBs in one big chunk fastly, and then continue stressing the system using allocation size of 16MB each 5 seconds. After this PR, the following is possible: stress -mem-total 5Gi -mem-alloc-size 16Mi -mem-alloc-sleep 5s -init-alloc-size 4Gi Signed-off-by: Itamar Holder <iholder@redhat.com>
