From 7749981ec31aa40e28a1ef5687e46bc1aa278fae Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Tue, 11 Jan 2011 07:24:23 -0500 Subject: cifs: remove code for setting timeouts on requests Since we don't time out individual requests anymore, remove the code that we used to use for setting timeouts on different requests.
