In lure of the sleepable-vs-non-sleepable anon-vma/i_mmap locking discussion, this patchset encapsulates the i_mmap_mutex lock into two functions to lock and unlock (for writting). This is very similar to how we currently deal with anon-vma lock, making it a lot easier to change the lock type. I've split these changes in to two patches since it makes patch 2 nicer to review, matching additions with deletions. Thanks!
