From fb1cfb88c8597d847553f39efc2bbd41c72c5f50 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Wed, 12 May 2010 11:42:29 -0400 Subject: [PATCH] fsnotify: initialize mask in fsnotify_perm akpm got a warning the fsnotify_mask could be used uninitialized in fsnotify_perm(). It's not actually possible but his compiler complained about it. This patch just initializes it to 0 to shut up the compiler.
