3.19.8-ckt5 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Grigori Goronzy <[email protected]> commit 54e03986133468e02cb01b76215e4d53a9cf6380 upstream. This was regressed by commit 39e7f6f8, although I don't know of any actual issues caused by it. The storage domain is read without TTM locking now, but the lock never helped to prevent any races.
