Patch series "Handle most file-backed faults under the VMA lock", v3. This patchset adds the ability to handle page faults on parts of files which are already in the page cache without taking the mmap lock. This patch (of 10): Provide lock_vma_under_rcu() when CONFIG_PER_VMA_LOCK is not defined to eliminate ifdefs in the users.
