3.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Jan Kara <[email protected]> commit 54c807e71d5ac59dee56c685f2b66e27cd54c475 upstream. Running AIO is pinning inode in memory using file reference. Once AIO is completed using aio_complete(), file reference is put and inode can be freed from memory. So we have to be sure that calling aio_complete() is the last thing we do with the inode.
