From: Brian Norris <computersforpeace@xxxxxxxxx> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know. =============== commit 299d0c5b27346a77a0777c993372bf8777d4f2e5 upstream. The comparison from the previous line seems to have been erroneously (partially) copied-and-pasted onto the next. The second line should be checking req.bytes, not req.lnum.
