From 869eb76e7b60ebd8f87a358b72e97fa0aef1d1f5 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Wed, 29 Jun 2005 18:52:28 -0400 Subject: [PATCH] [PATCH] reiserfs: Check if attrs are enabled for attr ioctls ReiserFS currently will allow the user to set/get attrs for files regardless if they are enabled. The patch checks to see if they are enabled, and returns -NOTTY if they are not. ext[23] doesn't need this check because attrs are always enabled.
