From d187663ef24cd3d033f0cbf2867e70b36a3a90b8 Mon Sep 17 00:00:00 2001 From: Julia Lawall <Julia.Lawall@lip6.fr> Date: Thu, 7 Jun 2012 15:45:00 -0700 Subject: [PATCH] fs/direct-io.c: adjust suspicious bit operation READ is 0, so the result of the bit-and operation is 0. Rewrite with == as done elsewhere in the same file. This problem was found using Coccinelle (http://coccinelle.lip6.fr/).
