From 90c81e0b0eda214196cbe4340facbce8cc797ee7 Mon Sep 17 00:00:00 2001 From: Steve French Date: Tue, 12 Feb 2008 20:32:36 +0000 Subject: [CIFS] clean up some hard to read ifdefs Christoph had noticed too many ifdefs in the CIFS code making it hard to read. This patch removes about a quarter of them from the C files in cifs by improving a few key ifdefs in the .h files.
