Andrew, thanks for getting that back in there.


mm-fix-fault-vs-invalidate-race-for-linear-mappings.patch broke ocfs2 shared
writable mmap. We hang on a page lock because ->page_mkwrite() is
being called with the page already locked:

+       /*
+        * For consistency in subsequent calls, make the nopage_page always
+        * locked.
+        */
+       if (unlikely(!(vma->vm_flags & VM_CAN_INVALIDATE)))
+               lock_page(nopage_page);

It wasn't previously being called with the page lock held, intentionally.
