Doug Ledford 3312d1c6bd RDMA/umem: Minor optimizations ... Noticed while reviewing commit d4b4dd1b97 ("RDMA/umem: Do not use current->tgid to track the mm_struct") patch. Why would we take a lock, adjust a protected variable, drop the lock, and *then* check the input into our protected variable adjustment? Then we have to take the lock again on our error unwind. Let's just check the input early and skip taking the locks needlessly if the input isn't valid. It was also noticed that we set mm = current->mm, we then never modify mm, but we still go back and reference current->mm a number of times needlessly. Be consistent in using the stored reference in mm.
