This is an effort to make the code simpler by making use of lock guards which were introduced in [1], which works by using __cleanup attributes. More details in v1 cover letter
This series aims mainly at simplifying code around mutex with goto statements. If it makes sense, there are more code simplification which can done for preempt, rcu, spinlock as well. Even for mutex, there is more which could be done. Even there are usecases for kfree which could use the new __free infra. Please review. Code is compile/boot tested except for powernv. Have kept the patches separate for easier bisect. Let me if they should be combined into one. Commit message is same for all.
