3.5.7.7 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Jan Kara <j...@suse.cz>
commit 9b171e0c74ca0549d0610990a862dd895870f04a 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.
