From 4065c802da7484fa36f8cdf10f18d087233ecb88 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 17 May 2010 07:18:58 -0400 Subject: cifs: fix noserverino handling when unix extensions are enabled The uniqueid field sent by the server when unix extensions are enabled is currently used sometimes when it shouldn't be. The readdir codepath is correct, but most others are not. Fix it.
